Ticker symbol
–
A ticker symbol or stock symbol is an abbreviation used to uniquely identify publicly traded shares of a particular stock on a particular stock market. A stock symbol may consist of letters, numbers or a combination of both, ticker symbol refers to the symbols that were printed on the ticker tape of a ticker tape machine. Stock symbols are unique identifiers assigned to each security traded on a particular market, for example, AAPL is for Apple Inc. OODH is for Orion DHC, Inc. and HD is for Home Depot, a stock symbol can consist of letters, numbers, or a combination of both, and is a way to uniquely identify that stock. The symbols were kept as short as possible to reduce the number of characters that had to be printed on the ticker tape, the allocation of symbols and formatting convention is specific to each stock exchange. In the US, for example, stock tickers are typically between 1 and 4 letters and represent the name where possible. In Europe, most exchanges use three-letter codes, for example Dutch consumer goods company Unilever traded on the Amsterdam Euronext exchange has the symbol UNA, while in Asia, numbers are often used as stock tickers to avoid issues for international investors when using non-Latin scripts. For example, the bank HSBCs stock traded on the Hong Kong Stock Exchange has the ticker symbol 0005, symbols sometimes change to reflect mergers. Prior to the 1999 merger with Mobil Oil, Exxon used a spelling of the company XON as its ticker symbol. The symbol of the firm after the merger was XOM, symbols are sometimes reused, in the US the single-letter symbols are particularly sought after as vanity symbols. For example, since Mar 2008 Visa Inc. has used the symbol V that had previously used by Vivendi which had delisted. To fully qualify a stock, both the ticker and the exchange or country of listing needs to be known, on many systems both must be specified to uniquely identify the security. This is often done by appending the location or exchange code to the ticker, although stock tickers identify a security, they are exchange dependent, generally limited to stocks and can change. These limitations have led to the development of other codes in financial markets to identify securities for settlement purposes, the most prevalent of these is the International Securities Identifying Number. An ISIN uniquely identifies a security and its structure is defined in ISO6166, Securities for which ISINs are issued include bonds, commercial paper, stocks, and warrants. The ISIN identifies the security, not the exchange on which it trades, for instance, Daimler AG stock trades on twenty-two different stock exchanges worldwide, and is priced in five different currencies, it has the same ISIN on each, though not the same ticker symbol. ISIN cannot specify a particular trade in this case, and another identifier, following the introduction of the Sequence trading platform in 1996, EPICs were renamed Tradable Instrument Display Mnemonics, but they are still widely referred to as EPICs. Stocks can also be identified using their SEDOL number or their ISIN, in the United States, modern letter-only ticker symbols were developed by Standard & Poors to bring a national standard to investing

NYSE MKT LLC, formerly known as the American Stock Exchange, is an American stock exchange situated in New York City, New York. AMEX was previously a mutual organization, owned by its members, until 1953, it was known as the New York Curb Exchange. On January 17,2008, NYSE Euronext announced it would acquire the AMEX for $260 million in stock, on October 1,2008, NYSE Euronext completed the acquisition. Before the closing of the acquisition, NYSE Euronext announced that the AMEX would be integrated with the Alternext European small-cap exchange, in March 2009, NYSE Alternext U. S. was changed to NYSE Amex Equities. On May 10,2012, NYSE Amex Equities changed its name to NYSE MKT LLC and these brokers often traded stocks that were speculative in nature. With the discovery of oil in the half of the 19th century. By 1865, following the American Civil War, stocks in small companies, such as iron and steel, textiles. Efforts to organize and standardize the market started early in the 20th century under Emanuel S. Mendels, in 1908, the New York Curb Market Agency was established, to codify trading practices. In 1911, the curbstone brokers came to be known as the New York Curb Market, after several years of outdoor trading, the curbstone brokers moved indoors in 1921 to New York Curb Exchange Building on Greenwich Street in Lower Manhattan. In 1929, the New York Curb Market changed its name to the New York Curb Exchange, within no time, the Curb Exchange became the leading international stock market, listing more foreign issues than all other U. S. securities markets combined. In 1953 the Curb Exchange was renamed the American Stock Exchange, in November 1972, Kolton was named as the exchanges first chief executive officer and its first salaried top executive. Kolton announced in July 1977 that he would be leaving his position at the American Exchange in November of that year, the American Stock Exchange merged with the New York Stock Exchange on October 1,2008. Post merger, the Amex equities business was branded NYSE Alternext US, as part of the re-branding exercise, NYSE Alternext US was re-branded as NYSE Amex Equities. On December 1,2008, the Curb Exchange building at 86 Trinity Place was closed, the Curbstone Brokers, The Origins of the American Stock Exchange. AMEX, A History of the American Stock Exchange

Computer hardware
–
Computer hardware is the collection of physical components that constitute a computer system. By contrast, software is instructions that can be stored and run by hardware, hardware is directed by the software to execute any command or instruction. A combination of hardware and software forms a usable computing system, the template for all modern computers is the Von Neumann architecture, detailed in a 1945 paper by Hungarian mathematician John von Neumann. The meaning of the term has evolved to mean a stored-program computer in which an instruction fetch and this is referred to as the Von Neumann bottleneck and often limits the performance of the system. For the third year, U. S. business-to-business channel sales increased. The impressive growth was the fastest sales increase since the end of the recession, sales growth accelerated in the second half of the year peaking in fourth quarter with a 6.9 percent increase over the fourth quarter of 2012. There are a number of different types of system in use today. The personal computer, also known as the PC, is one of the most common types of computer due to its versatility, laptops are generally very similar, although they may use lower-power or reduced size components, thus lower performance. The computer case is a plastic or metal enclosure that houses most of the components, a case can be either big or small, but the form factor of motherboard for which it is designed matters more. A power supply unit converts alternating current electric power to low-voltage DC power for the components of the computer. Laptops are capable of running from a battery, normally for a period of hours. The motherboard is the component of a computer. It is usually cooled by a heatsink and fan, or water-cooling system, most newer CPUs include an on-die Graphics Processing Unit. The clock speed of CPUs governs how fast it executes instructions, many modern computers have the option to overclock the CPU which enhances performance at the expense of greater thermal output and thus a need for improved cooling. The chipset, which includes the bridge, mediates communication between the CPU and the other components of the system, including main memory. Random-Access Memory, which stores the code and data that are being accessed by the CPU. For example, when a web browser is opened on the computer it takes up memory, RAM usually comes on DIMMs in the sizes 2GB, 4GB, and 8GB, but can be much larger. Read-Only Memory, which stores the BIOS that runs when the computer is powered on or otherwise begins execution, the BIOS includes boot firmware and power management firmware

Electronics

Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements, the science of electronics is also considered to be a branch of physics and electrical engineering. The ability of electronic devices to act as switches makes digital information processing possible, until 1950 this field was called radio technology because its principal application was the design and theory of radio transmitters, receivers, and vacuum tubes. Today, most electronic devices use semiconductor components to perform electron control and this article focuses on engineering aspects of electronics. Components are generally intended to be connected together, usually by being soldered to a circuit board. Components may be packaged singly, or in more complex groups as integrated circuits, some common electronic components are capacitors, inductors, resistors, diodes, transistors, etc. Components are often categorized as active or passive, vacuum tubes were among the earliest electronic components. They were almost solely responsible for the revolution of the first half of the Twentieth Century. They took electronics from parlor tricks and gave us radio, television, phonographs, radar, long distance telephony and they played a leading role in the field of microwave and high power transmission as well as television receivers until the middle of the 1980s. Since that time, solid state devices have all but completely taken over, vacuum tubes are still used in some specialist applications such as high power RF amplifiers, cathode ray tubes, specialist audio equipment, guitar amplifiers and some microwave devices. The 608 contained more than 3,000 germanium transistors, thomas J. Watson Jr. ordered all future IBM products to use transistors in their design. From that time on transistors were almost exclusively used for computer logic, circuits and components can be divided into two groups, analog and digital. A particular device may consist of circuitry that has one or the other or a mix of the two types, most analog electronic appliances, such as radio receivers, are constructed from combinations of a few types of basic circuits. Analog circuits use a range of voltage or current as opposed to discrete levels as in digital circuits. The number of different analog circuits so far devised is huge, especially because a circuit can be defined as anything from a single component, analog circuits are sometimes called linear circuits although many non-linear effects are used in analog circuits such as mixers, modulators, etc. Good examples of analog circuits include vacuum tube and transistor amplifiers, one rarely finds modern circuits that are entirely analog. These days analog circuitry may use digital or even microprocessor techniques to improve performance and this type of circuit is usually called mixed signal rather than analog or digital. Sometimes it may be difficult to differentiate between analog and digital circuits as they have elements of both linear and non-linear operation, an example is the comparator which takes in a continuous range of voltage but only outputs one of two levels as in a digital circuit

Toronto
–
Toronto is the most populous city in Canada and the provincial capital of Ontario. With a population of 2,731,571, it is the fourth most populous city in North America after Mexico City, New York City, and Los Angeles. A global city, Toronto is a centre of business, finance, arts, and culture. Aboriginal peoples have inhabited the area now known as Toronto for thousands of years, the city itself is situated on the southern terminus of an ancient Aboriginal trail leading north to Lake Simcoe, used by the Wyandot, Iroquois, and the Mississauga. Permanent European settlement began in the 1790s, after the broadly disputed Toronto Purchase of 1787, the British established the town of York, and later designated it as the capital of Upper Canada. During the War of 1812, the town was the site of the Battle of York, York was renamed and incorporated as the city of Toronto in 1834, and became the capital of the province of Ontario during the Canadian Confederation in 1867. The city proper has since expanded past its original borders through amalgamation with surrounding municipalities at various times in its history to its current area of 630.2 km2. While the majority of Torontonians speak English as their primary language, Toronto is a prominent centre for music, theatre, motion picture production, and television production, and is home to the headquarters of Canadas major national broadcast networks and media outlets. Toronto is known for its skyscrapers and high-rise buildings, in particular the tallest free-standing structure in the Western Hemisphere. The name Toronto is likely derived from the Iroquois word tkaronto and this refers to the northern end of what is now Lake Simcoe, where the Huron had planted tree saplings to corral fish. A portage route from Lake Ontario to Lake Huron running through this point, in the 1660s, the Iroquois established two villages within what is today Toronto, Ganatsekwyagon on the banks of the Rouge River and Teiaiagonon the banks of the Humber River. By 1701, the Mississauga had displaced the Iroquois, who abandoned the Toronto area at the end of the Beaver Wars, French traders founded Fort Rouillé on the current Exhibition grounds in 1750, but abandoned it in 1759. During the American Revolutionary War, the region saw an influx of British settlers as United Empire Loyalists fled for the British-controlled lands north of Lake Ontario, the new province of Upper Canada was in the process of creation and needed a capital. Dorchester intended the location to be named Toronto, in 1793, Governor John Graves Simcoe established the town of York on the Toronto Purchase lands, instead naming it after Prince Frederick, Duke of York and Albany. Simcoe decided to move the Upper Canada capital from Newark to York, the York garrison was constructed at the entrance of the towns natural harbour, sheltered by a long sandbar peninsula. The towns settlement formed at the end of the harbour behind the peninsula, near the present-day intersection of Parliament Street. In 1813, as part of the War of 1812, the Battle of York ended in the towns capture, the surrender of the town was negotiated by John Strachan. US soldiers destroyed much of the garrison and set fire to the parliament buildings during their five-day occupation, the sacking of York was a primary motivation for the Burning of Washington by British troops later in the war

Ontario
–
Ontario, one of the 13 provinces and territories of Canada, is located in east-central Canada. It is Canadas most populous province by a margin, accounting for nearly 40 percent of all Canadians. Ontario is fourth-largest in total area when the territories of the Northwest Territories and it is home to the nations capital city, Ottawa, and the nations most populous city, Toronto. There is only about 1 km of land made up of portages including Height of Land Portage on the Minnesota border. Ontario is sometimes divided into two regions, Northern Ontario and Southern Ontario. The great majority of Ontarios population and arable land is located in the south, in contrast, the larger, northern part of Ontario is sparsely populated with cold winters and is heavily forested. The province is named after Lake Ontario, a thought to be derived from Ontarí, io, a Huron word meaning great lake, or possibly skanadario. Ontario has about 250,000 freshwater lakes, the province consists of three main geographical regions, The thinly populated Canadian Shield in the northwestern and central portions, which comprises over half the land area of Ontario. Although this area mostly does not support agriculture, it is rich in minerals and in part covered by the Central and Midwestern Canadian Shield forests, studded with lakes, Northern Ontario is subdivided into two sub-regions, Northwestern Ontario and Northeastern Ontario. The virtually unpopulated Hudson Bay Lowlands in the north and northeast, mainly swampy. Southern Ontario which is further sub-divided into four regions, Central Ontario, Eastern Ontario, Golden Horseshoe, the highest point is Ishpatina Ridge at 693 metres above sea level located in Temagami, Northeastern Ontario. In the south, elevations of over 500 m are surpassed near Collingwood, above the Blue Mountains in the Dundalk Highlands, the Carolinian forest zone covers most of the southwestern region of the province. A well-known geographic feature is Niagara Falls, part of the Niagara Escarpment, the Saint Lawrence Seaway allows navigation to and from the Atlantic Ocean as far inland as Thunder Bay in Northwestern Ontario. Northern Ontario occupies roughly 87 percent of the area of the province. Point Pelee is a peninsula of Lake Erie in southwestern Ontario that is the southernmost extent of Canadas mainland, Pelee Island and Middle Island in Lake Erie extend slightly farther. All are south of 42°N – slightly farther south than the border of California. The climate of Ontario varies by season and location, the effects of these major air masses on temperature and precipitation depend mainly on latitude, proximity to major bodies of water and to a small extent, terrain relief. In general, most of Ontarios climate is classified as humid continental, Ontario has three main climatic regions

Canada
–
Canada is a country in the northern half of North America. Canadas border with the United States is the worlds longest binational land border, the majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its territory being dominated by forest and tundra. It is highly urbanized with 82 per cent of the 35.15 million people concentrated in large and medium-sized cities, One third of the population lives in the three largest cities, Toronto, Montreal and Vancouver. Its capital is Ottawa, and other urban areas include Calgary, Edmonton, Quebec City, Winnipeg. Various aboriginal peoples had inhabited what is now Canada for thousands of years prior to European colonization. Pursuant to the British North America Act, on July 1,1867, the colonies of Canada, New Brunswick and this began an accretion of provinces and territories to the mostly self-governing Dominion to the present ten provinces and three territories forming modern Canada. With the Constitution Act 1982, Canada took over authority, removing the last remaining ties of legal dependence on the Parliament of the United Kingdom. Canada is a parliamentary democracy and a constitutional monarchy, with Queen Elizabeth II being the head of state. The country is officially bilingual at the federal level and it is one of the worlds most ethnically diverse and multicultural nations, the product of large-scale immigration from many other countries. Its advanced economy is the eleventh largest in the world, relying chiefly upon its abundant natural resources, Canadas long and complex relationship with the United States has had a significant impact on its economy and culture. Canada is a country and has the tenth highest nominal per capita income globally as well as the ninth highest ranking in the Human Development Index. It ranks among the highest in international measurements of government transparency, civil liberties, quality of life, economic freedom, Canada is an influential nation in the world, primarily due to its inclusive values, years of prosperity and stability, stable economy, and efficient military. While a variety of theories have been postulated for the origins of Canada. In 1535, indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to the village of Stadacona, from the 16th to the early 18th century Canada referred to the part of New France that lay along the St. Lawrence River. In 1791, the area became two British colonies called Upper Canada and Lower Canada collectively named The Canadas, until their union as the British Province of Canada in 1841. Upon Confederation in 1867, Canada was adopted as the name for the new country at the London Conference. The transition away from the use of Dominion was formally reflected in 1982 with the passage of the Canada Act, later that year, the name of national holiday was changed from Dominion Day to Canada Day

Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

Jack Tramiel
–
Jack Tramiel was a Polish American businessman, best known for founding Commodore International. The Commodore PET, Commodore VIC-20 and Commodore 64 are some home computers produced while he was running the company, Tramiel later formed Atari Corporation after he purchased the remnants of the original Atari, Inc. from its parent company. Tramiel was born as Idek Trzmiel into a Jewish family, the son of Abram Josef Trzmiel, after the German invasion of Poland in 1939 his family was transported by German occupiers to the Jewish ghetto in Łódź, where he worked in a garment factory. When the ghettos were liquidated his family was sent to the Auschwitz concentration camp and he was examined by Josef Mengele and selected for a work party, after which he and his father were sent to the labor camp Ahlem near Hanover, while his mother remained at Auschwitz. Like many other inmates, his father was reported to have died of typhus in the camp, however. Tramiel was rescued from the camp in April 1945 by the 84th Infantry Division of the US army. On 10 November 1947, Tramiel immigrated to the United States and he soon joined the U. S. Army, where he learned how to repair office equipment, including typewriters. In 1953, while working as a driver, Tramiel bought a shop in the Bronx to repair office machinery. He named it Commodore Portable Typewriter, Tramiel wanted a military-style name for his company, but names such as Admiral and General were already taken, so he settled on the Commodore name. In 1955, Tramiel signed a deal with a Czechoslovak typewriter manufacturer Zbrojovka Brno NP to assemble, in 1962, Commodore went public, but the arrival of Japanese typewriters in the U. S. market made the selling of Czechoslovakian typewriters unprofitable. Stung twice by the source, Gould suggested that Tramiel travel to Japan to learn why they were able to outcompete North Americans in their own local markets. It was during this trip that Tramiel saw the first digital calculators, when Commodore released its first calculators, combining an LED display from Bowmar and an integrated circuit from Texas Instruments, it found a ready market. However, after realizing the size of the market, TI decided to cut Commodore out of the middle. When their lead designer, Chuck Peddle, told Tramiel that calculators were an end and computers were the future. Peddle responded with the Commodore PET, based on his companys MOS Technology 6502 processor and it was first shown, privately, at the Chicago Consumer Electronics Show in 1977, and soon the company was receiving 50 calls a day from dealers wanting to sell the computer. The PET became a success—especially in the field, where its all-in-one design was a major advantage. Much of their success with the PET came from the decision to sell directly to large customers. The first PET computers were sold primarily in Europe, where Commodore had also introduced the first wave of digital handheld calculators, Commodore responded with the VIC-20, and then the Commodore 64, which became the best-selling home computer of all time

Commodore PET
–
The Commodore PET is a line of home/personal computers produced starting in 1977 by Commodore International. The first model, which was named the PET2001, was the personal computer ever made available to retail consumers, after the Apple II. In the 1970s Commodore was one of many companies selling calculators designed around Dallas-based Texas Instruments chips. Commodore responded to this by searching for a set they could purchase outright. At Commodore, Peddle convinced Jack Tramiel that calculators were a dead-end, in September 1976 Peddle got a demonstration of Jobs and Wozniaks Apple II prototype, when Jobs was offering to sell it to Commodore, but Commodore considered Jobs offer too expensive. Tramiel demanded that Peddle, Bill Seiler, and John Feagans create a computer in time for the June 1977 Consumer Electronics Show, tramiels son, Leonard, helped design the PETSCII graphic characters and acted as quality control. The result was the first all-in-one home computer, the PET and its 6502 processor controlled the screen, keyboard, cassette tape recorders and any peripherals connected to one of the computers several expansion ports. The machine also included a built-in Datasette for data storage located on the front of the case, the data transfer rate to cassette tape was 1500 baud, but the data was recorded to tape twice for safety, giving an effective rate of 750 baud. The PET2001 was announced at the Winter CES in January 1977, however, the PET was back-ordered for months and to ease deliveries, early in 1978 Commodore decided to cancel the 4 kB version. However, this took six months to finally happen, during which time Microsoft lost money. At the end of the year, the company was saved by Apples decision to license Microsoft BASIC for the Apple II line. The key tops also tended to rub off easily, reliability was fairly poor, although that was not atypical of many early microcomputers. Because of the keyboard on the PET, external replacement ones quickly appeared. On the other hand, Commodore was a year behind Apple, in 1979, Commodore replaced the original PET2001 with an improved model known as the 2001-N. The new machine used a standard green-phosphor monitor in place of the blue in the original 2001. It now had a conventional, full-sized keyboard and no longer sported the built-in cassette recorder, the kernel ROM was upgraded to add support for Commodores newly introduced disk drive line. It was offered in 8kB, 16kB, or 32kB models as the 2001-N8, 2001-N16, the 2001-N switched to using conventional DRAM instead of the 6550 SRAM in the original model. PET 2001-8Ns had eight 2108 DRAMs and 2001-16Ns used sixteen 2108s, the PET4016 used eight 4116 chips

Commodore VIC-20
–
The VIC-20 is an 8-bit home computer that was sold by Commodore Business Machines. The VIC-20 was announced in 1980, roughly three years after Commodores first personal computer, the PET, the VIC-20 was the first computer of any description to sell one million units. The VIC-20 was intended to be more economical than the PET computer and it was equipped with 5 KB of static RAM and used the same MOS6502 CPU as the PET. As the Apple II gained momentum with the advent of VisiCalc in 1979, Jack Tramiel wanted a product that would compete in the same segment, for this reason Chuck Peddle and Bill Seiler started to design a computer named TOI. The TOI computer failed to materialize, mostly because it required an 80-column character display which in turn required the MOS Technology 6564 chip, however, the chip could not be used in the TOI since it required very expensive static RAM to operate fast enough. The serial IEEE 488-derivative CBM-488 interface was designed by Glen Stark, some features, like the memory add-in board, were designed by Bill Seiler. Altogether, the VIC20 development team consisted of five people, wed swipe whatever equipment we needed to get our jobs done. There was no way to get the work done. Theyd discover it was missing and they would just order more stuff from the warehouse, at the time, Commodore had an oversupply of 1 kbit×4 SRAM chips, so Tramiel decided that these should be used in the new computer. The end result was closer to the PET or TOI computers than to Yannes prototype. The original Revision A system board found in all silver-label VIC-20s used 2114 SRAMs and due to their tiny size, ten of them were required to reach 5k of system RAM. The Revision B system board, found in rainbow logo VIC-20s switched to larger 2048 byte SRAMs which reduced the count to five chips,2 x 2048 bytes chips +3 x 2114 chips. VIC-20s went through several variations in their 3-1/2 years of production, first-year models had a PET-style keyboard with a blocky font while most VIC-20s made during 1982 had a slightly different keyboard also shared with early C64s. The rainbow logo VIC-20 was introduced in early 1983 and has the newer C64 keyboard with gray function keys and it has a similar power supply to the C64 PSU, although the amperage is slightly lower. Older Revision A VIC-20s cannot use a C64 PSU or vice versa as their power requirement is too high, in April 1980, at a meeting of general managers outside London, Jack Tramiel declared that he wanted a low-cost color computer. When most of the GMs argued against it, he said, The Japanese are coming and this was in keeping with Tramiels philosophy which was to make computers for the masses, not the classes. Then, the project was given to Commodore Japan, a team led by Yash Terakura created the VIC-1001 for the Japanese market. The VIC-20 was marketed in Japan as VIC-1001 before VIC-20 was introduced to the US, when they returned to California from that meeting, Tomczyk wrote a 30-page memo detailing recommendations for the new computer, and presented it to Tramiel

The Commodore 64, also known as the C64, C-64, C=64, or occasionally CBM64 or VIC-64 in Sweden, is an 8-bit home computer introduced in January 1982 by Commodore International. It is listed in the Guinness World Records as the single computer model of all time. Volume production started in early 1982, marketing in August for US$595, preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its 64 kilobytes of RAM. It had superior sound and graphical specifications compared to earlier systems such as the Apple II and Atari 800, with multi-color sprites. The C64 dominated the low-end computer market for most of the 1980s. Sam Tramiel, a later Atari president and the son of Commodores founder, said in a 1989 interview, When I was at Commodore we were building 400,000 C64s a month for a couple of years. In the UK market, the C64 faced competition from the BBC Micro and the ZX Spectrum, part of the Commodore 64s success was its sale in regular retail stores instead of only electronics and/or computer hobbyist specialty stores. Commodore produced many of its parts in-house to control costs, including custom integrated circuit chips from MOS Technology and it has been compared to the Ford Model T automobile for its role in bringing a new technology to middle-class households via creative and affordable mass-production. Approximately 10,000 commercial software titles have made for the Commodore 64 including development tools, office productivity applications. C64 emulators allow anyone with a computer, or a compatible video game console. The C64 is also credited with popularizing the computer demoscene and is used today by some computer hobbyists. In 2008,17 years after it was taken off the market, in January 1981, MOS Technology, Inc. Commodores integrated circuit design subsidiary, initiated a project to design the graphic, Design work for the chips, named MOS Technology VIC-II and MOS Technology SID, was completed in November 1981. Commodore then began a game console project that would use the new chips—called the Ultimax or the Commodore MAX Machine and this project was eventually cancelled after just a few machines were manufactured for the Japanese market. At the same time, Robert Bob Russell and Robert Bob Yannes were critical of the current product line-up at Commodore, with the support of Al Charpentier and Charles Winterble, they proposed to Commodore CEO Jack Tramiel a true low-cost sequel to the VIC-20. Tramiel dictated that the machine should have 64 KB of random-access memory, although 64-Kbit dynamic random-access memory chips cost over US$100 at the time, he knew that DRAM prices were falling, and would drop to an acceptable level before full production was reached. The product was named the VIC-40 as the successor to the popular VIC-20. The team that constructed it consisted of Yash Terakura, Bob Russell, Bob Yannes, the design, prototypes and some sample software were finished in time for the show, after the team had worked tirelessly over both Thanksgiving and Christmas weekends

Commodore 128
–
The Commodore 128, also known as the C128, C-128, C=128, or occasionally CBM128, is the last 8-bit home computer that was commercially released by Commodore Business Machines. Introduced in January 1985 at the CES in Las Vegas, it appeared three years after its predecessor, the bestselling Commodore 64, the C128 is a significantly expanded successor to the C64, with nearly full compatibility. The newer machine has 128 kB of RAM in two 64 kB banks, and an 80-column color video output and it has a redesigned case and keyboard. Also included is a Zilog Z80 CPU which allows the C128 to run CP/M, the presence of the Z80 and the huge CP/M software library it brings, coupled with the C64s software library, gives the C128 one of the broadest ranges of available software among its competitors. The primary hardware designer of the C128 was Bil Herd, who had worked on the Plus/4, other hardware engineers were Dave Haynie and Frank Palaia, while the IC design work was done by Dave DiOrio. The main Commodore system software was developed by Fred Bowen and Terry Ryan, the C128s keyboard includes four cursor keys, an Alt key, Help key, Esc key, Tab key and a numeric keypad. None of these were present on the C64, previous Commodores had only two cursor keys, which required using the Shift key to move the cursor up or left. This alternate arrangement was retained on the 128, for use under C64 mode, the lack of a numeric keypad, Alt key, and Esc key on the C64 was an issue with some CP/M productivity software when used with the C64s Z80 cartridge. A keypad was requested by many C64 owners who spent long hours entering machine language programs using MLX, many of the added keys matched counterparts present on the IBM PCs keyboard and made the new computer more attractive to business software developers. While the 128s 40-column mode closely duplicates that of the C64, the C128s power supply is improved over the C64s unreliable design, being much larger and equipped with cooling vents and a replaceable fuse. The C128 does not perform a system RAM test on power-up like previous Commodore machines, instead of the single 6510 microprocessor of the C64, the C128 incorporates a two-CPU design. The primary CPU, the 8502, is an improved version of the 6510. The second CPU is a Zilog Z80 which is used to run CP/M software, the two processors cannot run concurrently, thus the C128 is not a multiprocessing system. The C128s complex architecture includes four differently accessed kinds of RAM, early versions of the C128 occasionally experience temperature-related reliability issues due to the use of an electromagnetic shield over the main circuit board. The shield was equipped with fingers that contacted the tops of the major chips, the SID sound chip is particularly vulnerable in this respect. The most common remedy is to remove the shield, which Commodore had added late in development in order to comply with FCC radio-frequency regulations, the C128 has three operating modes. C128 Mode runs at 1 or 2 MHz with the 8502 CPU and has both 40- and 80-column text modes available, CP/M Mode uses both the Z80 and the 8502 and is able to function in both 40- or 80-column text mode. C64 Mode is nearly 100 percent compatible with the earlier computer, selection of these modes is implemented via the Z80 chip

Amiga
–
The Amiga is a family of personal computers sold by Commodore in the 1980s and 1990s. The Amiga provided a significant upgrade from earlier 8-bit home computers, the Amiga 1000 was officially released in July 1985, but a series of production problems meant it did not become widely available until early 1986. The best selling model, the Amiga 500, was introduced in 1987 and became one of the home computers of the late 1980s. The A3000, introduced in 1990, started the second generation of Amiga systems, followed by the A500+, finally, as the third generation, the A1200 and the A4000 were released in late 1992. The platform became particularly popular for gaming and programming demos and it also found a prominent role in the desktop video, video production, and show control business, leading to video editing systems such as the Video Toaster. The Amigas native ability to play back multiple digital sound samples made it a popular platform for early tracker music software. It was also an expensive alternative to the Apple Macintosh. Initially, the Amiga was developed alongside various Commodore PC clones, Commodore ultimately went bankrupt in April 1994 after the Amiga CD32 model failed in the marketplace. Since the demise of Commodore, various groups have marketed successors to the original Amiga line, including Genesi, Eyetech, ACube Systems Srl, likewise, AmigaOS has influenced replacements, clones and compatible systems such as MorphOS, AmigaOS4 and AROS. The Amiga was so far ahead of its time that almost nobody—including Commodores marketing department—could fully articulate what it was all about. Today, its obvious the Amiga was the first multimedia computer, but in those days it was derided as a machine because few people grasped the importance of advanced graphics, sound. Nine years later, vendors are still struggling to make systems that work like 1985 Amigas, Jay Miner joined Atari in the 1970s to develop custom integrated circuits, and led development of the Atari 2600s TIA. Almost as soon as its development was complete, the team developing a much more sophisticated set of chips, CTIA, ANTIC and POKEY. With the 8-bit lines launch in 1979, Miner again started looking at a next generation chipset, Miner wanted to start work with the new Motorola 68000, but management was only interested in another MOS6502 based system. Miner left the company, and the industry, shortly thereafter, in 1982, Larry Kaplan was approached by a number of investors who wanted to develop a new game platform. Kaplan hired Miner to run the side of the newly formed company. The system was code-named Lorraine in keeping with Miners policy of giving systems female names, in case the company presidents wife. When Kaplan left the late in 1982 to rejoin Atari, Miner was promoted to head engineer

Home computer
–
Home computers were a class of microcomputers entering the market in 1977, and becoming common during the 1980s. They were marketed to consumers as affordable and accessible computers that, however, a home computer often had better graphics and sound than contemporaneous business computers. Their most common uses were playing games, but they were also regularly used for word processing, doing homework. Home computers were usually not electronic kits, home computers were already manufactured in stylish metal or plastic enclosures. There were, however, commercial kits like the Sinclair ZX80 which were home and home-built computers since the purchaser could assemble the unit from a kit. For example, using a typical 1980s home computer as a home automation appliance would require the computer to be powered on at all times. Personal finance and database use required tedious data entry, by contrast, advertisements in the specialty computer press often simply listed specifications. Since most systems shipped with the BASIC programming language included on the system ROM, many users found programming to be a fun and rewarding experience, and an excellent introduction to the world of digital technology. Often the only difference may be the outlet through which they are purchased. Another change from the computer era is that the once-common endeavour of writing ones own software programs has almost vanished from home computer use. As early as 1965, some projects such as Jim Sutherlands ECHO IV explored the possible utility of a computer in the home. In 1969, the Honeywell Kitchen Computer was marketed as a gift item, and would have inaugurated the era of home computing. Computers became affordable for the public in the 1970s due to the mass production of the microprocessor starting in 1971. Early microcomputers such as the Altair 8800 had front-mounted switches and diagnostic lights to control and indicate internal system status, while two early home computers could be bought either in kit form or assembled, most home computers were only sold pre-assembled. The keyboard - a feature lacking on the Altair - was usually built into the case as the motherboard. Ports for plug-in peripheral devices such as a display, cassette tape recorders, joysticks. Usually the manufacturer would sell peripheral devices designed to be compatible with their computers as extra cost accessories, peripherals were not often interchangeable between different brands of home computer, or even between successive models of the same brand. To save the cost of a monitor, the home computer would often connect through an RF modulator to the family TV set

Personal computer
–
A personal computer is a multi-purpose electronic computer whose size, capabilities, and price make it feasible for individual use. PCs are intended to be operated directly by a end-user, rather than by an expert or technician. In the 2010s, PCs are typically connected to the Internet, allowing access to the World Wide Web, personal computers may be connected to a local area network, either by a cable or a wireless connection. In the 2010s, a PC may be, a multi-component desktop computer, designed for use in a location a laptop computer, designed for easy portability or a tablet computer. In the 2010s, PCs run using a system, such as Microsoft Windows, Linux. The very earliest microcomputers, equipped with a front panel, required hand-loading of a program to load programs from external storage. Before long, automatic booting from permanent read-only memory became universal, in the 2010s, users have access to a wide range of commercial software, free software and free and open-source software, which are provided in ready-to-run or ready-to-compile form. Since the early 1990s, Microsoft operating systems and Intel hardware have dominated much of the computer market, first with MS-DOS. Alternatives to Microsofts Windows operating systems occupy a minority share of the industry and these include Apples OS X and free open-source Unix-like operating systems such as Linux and Berkeley Software Distribution. Advanced Micro Devices provides the alternative to Intels processors. PC is an initialism for personal computer, some PCs, including the OLPC XOs, are equipped with x86 or x64 processors but not designed to run Microsoft Windows. PC is used in contrast with Mac, an Apple Macintosh computer and this sense of the word is used in the Get a Mac advertisement campaign that ran between 2006 and 2009, as well as its rival, Im a PC campaign, that appeared in 2008. Since Apples transition to Intel processors starting 2005, all Macintosh computers are now PCs, the “brain” may one day come down to our level and help with our income-tax and book-keeping calculations. But this is speculation and there is no sign of it so far, in the history of computing there were many examples of computers designed to be used by one person, as opposed to terminals connected to mainframe computers. Using the narrow definition of operated by one person, the first personal computer was the ENIAC which became operational in 1946 and it did not meet further definitions of affordable or easy to use. An example of an early single-user computer was the LGP-30, created in 1956 by Stan Frankel and used for science and it came with a retail price of $47, 000—equivalent to about $414,000 today. Introduced at the 1965 New York Worlds Fair, the Programma 101 was a programmable calculator described in advertisements as a desktop computer. It was manufactured by the Italian company Olivetti and invented by the Italian engineer Pier Giorgio Perotto, the Soviet MIR series of computers was developed from 1965 to 1969 in a group headed by Victor Glushkov

Auschwitz concentration camp
–
Auschwitz concentration camp was a network of German Nazi concentration camps and extermination camps built and operated by the Third Reich in Polish areas annexed by Nazi Germany during World War II. It consisted of Auschwitz I, Auschwitz II–Birkenau, Auschwitz III–Monowitz, Auschwitz I was first constructed to hold Polish political prisoners, who began to arrive in May 1940. The first extermination of prisoners took place in September 1941, from early 1942 until late 1944, transport trains delivered Jews to the camps gas chambers from all over German-occupied Europe, where they were killed with the pesticide Zyklon B. An estimated 1.3 million people were sent to the camp, around 90 percent of those killed were Jewish, approximately 1 in 6 Jews killed in the Holocaust died at the camp. Many of those not killed in the gas chambers died of starvation, forced labor, infectious diseases, individual executions, and medical experiments. In the course of the war, the camp was staffed by 7,000 members of the German Schutzstaffel, some, including camp commandant Rudolf Höss, were executed. The Allied Powers refused to believe reports of the atrocities at the camp. As Soviet troops approached Auschwitz in January 1945, most of its population was sent west on a death march, the prisoners remaining at the camp were liberated on 27 January 1945, a day now commemorated as International Holocaust Remembrance Day. In the following decades, survivors, such as Primo Levi, Viktor Frankl, and Elie Wiesel, wrote memoirs of their experiences in Auschwitz, and the camp became a dominant symbol of the Holocaust. In 1947, Poland founded the Auschwitz-Birkenau State Museum on the site of Auschwitz I and II, immediately after the Nazi seizure of power in Germany, acts of violence perpetrated against Jews became ubiquitous. The Law for the Restoration of the Professional Civil Service, passed on 7 April 1933 excluded most Jews from the legal profession, similar legislation soon deprived Jewish members of other professions of the right to practise. Harassment and economic pressure were used by the regime to encourage Jews to leave the country voluntarily and their businesses were denied access to markets, forbidden to advertise in newspapers, and deprived of government contracts. German Jews were subjected to violent attacks and boycotts, in September 1935 the Nuremberg Laws were enacted. The Reich Citizenship Law stated that only those of Germanic or related blood were defined as citizens, thus Jews and other minority groups were stripped of their German citizenship. The laws were expanded on 26 November 1935 to include Romani people and this supplementary decree defined Gypsies as enemies of the race-based state, the same category as Jews. By the start of World War II in 1939, around 250,000 of Germanys 437,000 Jews had emigrated to the United States, Palestine, the United Kingdom, Nazi Germany invaded Poland in September 1939. German dictator Adolf Hitler ordered that the Polish leadership and intelligentsia be destroyed, approximately 65,000 civilians, who were viewed as being inferior to the Aryan master race, were killed by the end of 1939. In addition to leaders of Polish society, the Nazis killed Jews, prostitutes, Romani, sS-Obergruppenführer Reinhard Heydrich, then head of the Gestapo, ordered on 21 September that Polish Jews should be rounded up and concentrated into cities with good rail links

Adding machine
–
An adding machine was a class of mechanical calculator, usually specialized for bookkeeping calculations. In the United States, the earliest adding machines were built to read in dollars. Adding machines were ubiquitous office equipment until they were phased out in favor of calculators in the 1970s, the older adding machines were rarely seen in American office settings by the year 2000. However, they did not gain widespread use until Dorr E. Felt started manufacturing his comptometer, to add a new list of numbers and arrive at a total, the user was first required to ZERO the machine. Then, to add sets of numbers, the user was required to press numbered keys on a keyboard, which would remain depressed. The user would then pull the crank, which caused the numbers to be shown on the wheels. The rotary wheels now showed 3072, press the 4 key in the 3rd column from the right, the 4 key in the 2nd column from right, and the 9 key in the rightmost column. The rotary wheels now show a total of 3521 which. Keyboards typically did not have or need 0 keys, one simply did not press any key in the column containing a zero, trailing zeros, were there by default because when a machine was zeroed, all numbers visible on the rotary wheels were reset to zero. Subtraction was impossible, except by adding the complement of a number, multiplication was a simple process of keying in the numbers one or more columns to the left and repeating the addition process. For example, to multiply 34.72 by 102, key in 3472, pull crank, wheels now show 354144, or 3,541.44 A later adding machine, called the comptometer, did not require that a crank be pulled to add. Numbers were input simply by pressing keys, the machine was thus driven by finger power. Multiplication was similar to that on the machine, but users would form up their fingers over the keys to be pressed. Using the above example, four fingers would be used to press down twice on the 3,4,7 and 2 keys and that finger shape would then move left two columns and press once. Usually a small crank near the wheels would be used to zero them, some adding machines were electromechanical — an old-style mechanism, but driven by electric power. Some ten-key machines had input of numbers as on a modern calculator –30.72 was input as 3,0,7,2 and these machines could subtract as well as add. Some could multiply and divide, although including these operations made the more complex. Those that could multiply, used a form of the old adding machine multiplication method, using the previous example of multiplying 34.72 by 102, the amount was keyed in, then the 2 key in the multiplication key column was pressed

New York Stock Exchange
–
The New York Stock Exchange, is an American stock exchange located at 11 Wall Street, Lower Manhattan, New York City, New York. It is by far the worlds largest stock exchange by market capitalization of its companies at US$19.3 trillion as of June 2016. The average daily trading value was approximately US$169 billion in 2013, the NYSE trading floor is located at 11 Wall Street and is composed of 21 rooms used for the facilitation of trading. A fifth trading room, located at 30 Broad Street, was closed in February 2007, the main building and the 11 Wall Street building were designated National Historic Landmarks in 1978. The NYSE is owned by Intercontinental Exchange, an American holding company that it also lists, previously, it was part of NYSE Euronext, which was formed by the NYSEs 2007 merger with Euronext. NYSE and Euronext now operate as divisions of Intercontinental Exchange, the NYSE has been the subject of several lawsuits regarding fraud or breach of duty and in 2004 was sued by its former CEO for breach of contract and defamation. The earliest recorded organization of securities trading in New York among brokers directly dealing with each other can be traced to the Buttonwood Agreement, previously securities exchange had been intermediated by the auctioneers who also conducted more mundane auctions of commodities such as wheat and tobacco. In 1817 the stockbrokers of New York operating under the Buttonwood Agreement instituted new reforms, after sending a delegation to Philadelphia to observe the organization of their board of brokers, restrictions on manipulative trading were adopted as well as formal organs of governance. Several locations were used between 1817 and 1865, when the present location was adopted, the invention of the electrical telegraph consolidated markets, and New Yorks market rose to dominance over Philadelphia after weathering some market panics better than other alternatives. The Civil War greatly stimulated speculative securities trading in New York, by 1869 membership had to be capped, and has been sporadically increased since. The latter half of the century saw rapid growth in securities trading. Securities trade in the nineteenth and early twentieth centuries was prone to panics. The Stock Exchange Luncheon Club was situated on the floor from 1898 until its closure in 2006. The main building, located at 18 Broad Street, between the corners of Wall Street and Exchange Place, was designated a National Historic Landmark in 1978, as was the 11 Wall Street building. The NYSE announced its plans to merge with Archipelago on April 21,2005, NYSEs governing board voted to merge with rival Archipelago on December 6,2005, and became a for-profit, public company. It began trading under the name NYSE Group on March 8,2006, Wall Street is the leading US money center for international financial activities and the foremost US location for the conduct of wholesale financial services. It comprises a matrix of wholesale financial sectors, financial markets, financial institutions, the principal sectors are securities industry, commercial banking, asset management, and insurance. Prior to the acquisition of NYSE Euronext by the ICE in 2013, Marsh Carter was the Chairman of the NYSE, presently, the chairman is Jeffrey Sprecher

Calculator
–
An electronic calculator is a small, portable electronic device used to perform operations ranging from basic arithmetic to complex mathematics. The first solid state electronic calculator was created in the 1960s, building on the history of tools such as the abacus. It was developed in parallel with the computers of the day. The pocket sized devices became available in the 1970s, especially after the first microprocessor and they later became used commonly within the petroleum industry. Modern electronic calculators vary, from cheap, give-away, credit-card-sized models to sturdy desktop models with built-in printers and they became popular in the mid-1970s. By the end of decade, calculator prices had reduced to a point where a basic calculator was affordable to most. In addition to general purpose calculators, there are designed for specific markets. For example, there are scientific calculators which include trigonometric and statistical calculations, some calculators even have the ability to do computer algebra. Graphing calculators can be used to graph functions defined on the real line, as of 2016, basic calculators cost little, but the scientific and graphing models tend to cost more. In 1986, calculators still represented an estimated 41% of the worlds general-purpose hardware capacity to compute information, by 2007, this diminished to less than 0. 05%. Modern 2016 electronic calculators contain a keyboard with buttons for digits and arithmetical operations, most basic calculators assign only one digit or operation on each button, however, in more specific calculators, a button can perform multi-function working with key combinations. Large-sized figures and comma separators are used to improve readability. Various symbols for function commands may also be shown on the display, fractions such as 1⁄3 are displayed as decimal approximations, for example rounded to 0.33333333. Also, some fractions can be difficult to recognize in decimal form, as a result, Calculators also have the ability to store numbers into computer memory. Basic types of these only one number at a time. The variables can also be used for constructing formulas, some models have the ability to extend memory capacity to store more numbers, the extended memory address is termed an array index. Power sources of calculators are, batteries, solar cells or mains electricity, some models even have no turn-off button but they provide some way to put off. Crank-powered calculators were also common in the computer era

Texas Instruments
–
Texas Instruments Inc. is an American technology company that designs and manufactures semiconductors, which it sells to electronics designers and manufacturers globally. Headquartered in Dallas, Texas, United States, TI is one of the top ten semiconductor companies worldwide, Texas Instrumentss focus is on developing analog chips and embedded processors, which accounts for more than 85% of their revenue. TI also produces TI digital light processing technology and education technology products including calculators, microcontrollers, to date, TI has more than 43,000 patents worldwide. TI produced the worlds first commercial silicon transistor in 1950, Jack Kilby invented the integrated circuit in 1958 while working at TIs Central Research Labs. TI also invented the hand-held calculator in 1967, and introduced the first single-chip microcontroller in 1970, in 1987, TI invented the digital light processing device, which serves as the foundation for the companys award-winning DLP technology and DLP Cinema. In 1990, TI came out with the popular TI-81 calculator which made them a leader in the calculator industry. In 1997, its business was sold to Raytheon, which allowed TI to strengthen its focus on digital solutions. Texas Instruments was founded by Cecil H. Green, J. Erik Jonsson, Eugene McDermott, McDermott was one of the original founders of Geophysical Service Inc. in 1930. McDermott, Green, and Jonsson were GSI employees who purchased the company in 1941, in November,1945, Patrick Haggerty was hired as general manager of the Laboratory and Manufacturing division, which focused on electronic equipment. By 1951, the L&M division, with its contracts, was growing faster than GSIs Geophysical division. The company was reorganized and initially renamed General Instruments Inc, because there already existed a firm named General Instrument, the company was renamed Texas Instruments that same year. From 1956 to 1961, Fred Agnich of Dallas, later a Republican member of the Texas House of Representatives, was the Texas Instruments president, Geophysical Service, Inc. became a subsidiary of Texas Instruments. Early in 1988 most of GSI was sold to the Halliburton Company, in 1930, J. Clarence Karcher and Eugene McDermott founded Geophysical Service, an early provider of seismic exploration services to the petroleum industry. In 1939, the company reorganized as Coronado Corp. an oil company with Geophysical Service Inc, on December 6,1941, McDermott along with three other GSI employees, J. Erik Jonsson, Cecil H. Green, and H. B. During World War II, GSI expanded their services to include electronics for the U. S. Army, Signal Corps, in 1951, the company changed its name to Texas Instruments, GSI becoming a wholly owned subsidiary of the new company. Texas Instruments also continued to manufacture equipment for use in the seismic industry, after selling GSI, TI finally sold the company to Halliburton in 1988, at which point GSI ceased to exist as a separate entity. Texas Instruments entered the electronics market in 1942 with submarine detection equipment. During the early 1980s, Texas Instruments instituted a quality program which included Juran training, as well as promoting statistical process control, Taguchi methods and Design for Six Sigma

MOS Technology
–
MOS Technology, Inc. also known as CSG, was a semiconductor design and fabrication company based in Norristown, Pennsylvania, in the United States. It is most famous for its 6502 microprocessor and various designs for Commodore Internationals range of home computers, MOS Technology, Inc. was originally started in 1969 by Allen-Bradley to provide a second source for electronic calculators and their chips designed by Texas Instruments. Many early chip companies were wiped out in the aftermath, those that survived did so by finding other chips to produce, MOS became a supplier to Atari, producing a custom single-chip Pong system. Several of the designers of the Motorola 6800 left Motorola shortly after its release, at the time there was no such thing as a design-only firm, so they had to join a chip-building company to produce their new CPU. MOS was a firm with good credentials in the right area. The team of four design engineers was headed by Chuck Peddle, at MOS they set about building a new CPU that would outperform the 6800 while being similar to it in purpose. The resulting 6501 design was similar to the 6800, but by using several simplifications in the design. In addition to a design, MOS had a secret weapon. Masks are the drawings of the chip that are photo-reduced to make the pattern from which chips are made—a process similar to photocopying. All masks end up with flaws, both as a result of problems in the chip itself, as well as side effects from the photo-reduction process. When a chip is made with this there is a chance that some of these flaws will end up expressed on the chip. If too many of them are expressed, that particular chip will not work, so companies simply built chips with known-bad masks, and threw away broken chips. In the 1970s, this meant throwing away 70 percent or more of the completed chips. The price of a chip is largely defined by the yield, MOSs engineers had learned the trick of fixing their masks after they were made. This allowed them to correct the flaws in a series of small fixes. This meant that not only were its designs faster, they cost much less as well, when the 6501 was announced, Motorola launched a lawsuit almost immediately. That was enough to allow Motorola to sue, sales of the 6501 basically stopped, and the lawsuit would drag on for many years before MOS was eventually forced to pay $200,000 USD in fines. In the meantime MOS had started selling the 6502, a capable of operating at 1 MHz in September 1975 for a mere $25 USD

Computer History Museum
–
The Computer History Museum is a museum established in 1996 in Mountain View, California, US. The Museum is dedicated to preserving and presenting the stories and artifacts of the information age, the museums origins date to 1968 when Gordon Bell began a quest for a historical collection and, at that same time, others were looking to preserve the Whirlwind computer. The resulting Museum Project had its first exhibit in 1975, located in a coat closet in a DEC lobby. In 1978, the museum, now The Digital Computer Museum, moved to a larger DEC lobby in Marlborough, maurice Wilkes presented the first lecture at TDCM in 1979 – the presentation of such lectures has continued to the present time. TDCM incorporated as The Computer Museum in 1982, in 1984, TCM moved to Boston, locating on Museum Wharf. In 1996/1997, The TCM History Center in Silicon Valley was established, a site at Moffett Field was provided by NASA, in 1999, TCMHC incorporated and TCM ceased operation, shipping its remaining artifacts to TCMHC in 2000. The name TCM had been retained by the Boston Museum of Science so, in 2000, in 2003, CHM opened its new building, at 1401 N. Shoreline Blvd in Mountain View, California, to the public. The facility was heavily renovated and underwent a two-year $19 million makeover before reopening on January 2011. The Computer History Museum claims to house the largest and most significant collection of computing artifacts in the world, the collection comprises nearly 90,000 objects, photographs and films, as well as 4,000 feet of cataloged documentation and several hundred gigabytes of software. The CHM oral history program conducts video interviews around the history of computing and networking, the museums 25, 000-square-foot exhibit Revolution, The First 2000 Years of Computing, opened to the public on January 13,2011. It covers the history of computing in 20 galleries, from the abacus to the Internet, the entire exhibition is also available online. The museum features a Liquid Galaxy in the “Going Places, A History of Silicon Valley” exhibit, the exhibit features 20 preselected locations that visitors can fly to on the Liquid Galaxy. An operating Difference Engine designed by Charles Babbage in the 1840s and it had been on loan since 2008 from its owner, Nathan Myhrvold, a former Microsoft executive.

Mountain View, California
–
Mountain View is a city located in Santa Clara County, California, United States, named for its views of the Santa Cruz Mountains. From its origins as a stop, it grew to a large suburb with a pedestrian-friendly downtown, free wi-fi. The city borders Palo Alto and the San Francisco Bay to the north, Los Altos to the south, situated in the southern end of the San Francisco Peninsula in the San Francisco Bay Area, Mountain View is home to many high technology companies. In 1956, Shockley Semiconductor Laboratory, the first company to develop silicon semiconductor devices in what came to be known as Silicon Valley, was established in the city by William Shockley. Today, many of the largest technology companies in the world are headquartered in the city, including Google, Mozilla Foundation, Symantec, and Intuit. The original Byte Shop computer store was opened at 1063 El Camino Real, Mountain View by Paul Terrell, the Santa Clara Valley Transportation Authority integrates the city with the neighboring cities of Palo Alto, Los Altos, and Sunnyvale. The Mexican land grant of Rancho Pastoria de las Borregas was given in 1842 by Alta California Governor Juan Alvarado to Francisco Estrada. This grant was passed on to Mariano Castro, who sold half of the land to Martin Murphy, Jr. Eventually. First known as the center of Fremont Twp. before the first California 1852 census. Which meant that it was a predecessor to Mayfield and Palo Alto, Mountain View Station, officially named in 1864, had its beginnings earlier as a stagecoach stop on the route between San Francisco and San Jose, including the Butterfield Overland Mail. & El Camino Real of today, was closer to what was once the town center. The early pioneers were buried at the old cemetery between Mercy & Church, off Castro Street, now the present city Library and park. Reverend Henry Merrill Henderson, born in Maryland, age 35, arrived in Spring of 1852, with his family to meet with relatives Ricketts and he was the first Baptist minister in town and soon was going by horse to Half-Moon Bay, and McCartersville for services. His next-door neighbor arrived later that year, Seligman Weilheimer and brother Samuel from Dossenheim, Baden, Germany, who built at that property, the Fremont twp. population was about 560 by 1860, less Mayfield Post office section, which began north of present San Antonio Road. The towns early growth was due to agriculture, William Bubb later being a figure, buying 80 acres to farm in October 1851. His heirs expanded and intermarried in the area, agriculture remained the primary industry into the middle of the 20th century. The U. S. Navys adjacent 1000 acre Moffet Field Complex began after 1931, after World War II, the population grew significantly with the development of the aerospace and electronics industries. Between 1950 and 1960, the population grew from 6,563 to 30,889, today, high technology is the foundation of the local economy, and there exist few remnants of the citys agricultural past

General Electric
–
General Electric, often abbreviated as GE, is an American multinational conglomerate corporation incorporated in New York and headquartered in Boston, Massachusetts. In 2011, GE ranked among the Fortune 500 as the 68th-largest firm in the U. S. by gross revenue, as of 2012, the company was listed the fourth-largest in the world among the Forbes Global 2000, further metrics being taken into account. The Nobel Prize has twice been awarded to employees of General Electric, Irving Langmuir in 1932, on January 13,2016, it was announced that GE will be moving its corporate headquarters from Fairfield, Connecticut to the South Boston Waterfront neighborhood of Boston, Massachusetts. The first group of workers arrived in the summer of 2016, morgan and the Vanderbilt family for Edisons lighting experiments. The new company also acquired Sprague Electric Railway & Motor Company in the same year, both plants continue to operate under the GE banner to this day. The company was incorporated in New York, with the Schenectady plant used as headquarters for years thereafter. Around the same time, General Electrics Canadian counterpart, Canadian General Electric, was formed, in 1896, General Electric was one of the original 12 companies listed on the newly formed Dow Jones Industrial Average. After 120 years, it is the one of the original companies still listed on the Dow index. In 1911, General Electric absorbed the National Electric Lamp Association into its lighting business, GE established its lighting division headquarters at Nela Park in East Cleveland, Ohio. Nela Park is still the headquarters for GEs lighting business, owen D. Young, through GE, founded the Radio Corporation of America in 1919 to further international radio. GE used RCA as its retail arm for radio sales from 1919, in 1927, Ernst Alexanderson of GE made the first demonstration of his television broadcasts at his General Electric Realty Plot home at 1132 Adams Rd, Schenectady, NY. The sound was broadcast on GEs WGY, experimental television station W2XAD evolved into station WRGB which—along with WGY and WGFM —was owned and operated by General Electric until 1983. GEs history of working with turbines in the field gave them the engineering know-how to move into the new field of aircraft turbosuperchargers. Led by Sanford Alexander Moss, GE introduced the first superchargers during World War I, superchargers became indispensable in the years immediately prior to World War II, and GE was the world leader in exhaust-driven supercharging when the war started. This experience, in turn, made GE a natural selection to develop the Whittle W.1 jet engine that was demonstrated in the United States in 1941, GE ranked ninth among United States corporations in the value of wartime production contracts. In 2002, GE acquired the assets of Enron during its bankruptcy proceedings. Some consumers boycotted GE light bulbs, refrigerators and other products in the 1980s and 1990s to protest GEs role in weapons production. With IBM, Burroughs, NCR, Control Data Corporation, Honeywell, RCA and UNIVAC, GE had a line of general purpose and special purpose computers

General Motors
–
With global headquarters at the Renaissance Center in Detroit, Michigan, United States, GM manufactures cars and trucks in 35 countries. In 2008,8.35 million GM cars and trucks were sold globally under various brands, current auto brands are Buick, Cadillac, Chevrolet, GMC, Holden, and Wuling. Former GM automotive brands include McLaughlin, Oakland, Oldsmobile, Pontiac, Hummer, Saab, Saturn, Vauxhall, the company was founded by William C. Durant on September 16,1908 as a holding company. The company was the largest automobile manufacturer from 1931 through 2007, in addition to brands selling assembled vehicles, GM also has had various automotive-component and non-automotive brands, many of which it divested in the 1980s through 2000s. General Motors produces vehicles in 37 countries under twelve brands, Chevrolet, Buick, GMC, Cadillac, Holden, HSV, Opel, Vauxhall, Wuling, Baojun, Jie Fang, and Ravon. The current company, General Motors Company LLC, was formed in 2009 following the bankruptcy of General Motors Corporation, the new company purchased the majority of the assets of the old GM, including the brand General Motors. In addition to its twelve brands, General Motors also holds a 20% stake in IMM, General Motors employs 212,000 people and does business in more than 140 countries. General Motors is divided into five segments, GM North America, Opel Group, GM International Operations, GM South America. General Motors led global vehicle sales for 77 consecutive years from 1931 through 2007, longer any other automaker. General Motors acts in most countries outside the U. S. via wholly owned subsidiaries, GMs OnStar subsidiary provides vehicle safety, security and information services. In 2009, General Motors shed several brands, closing Saturn, Pontiac, and Hummer, in 2010, the reorganized GM made an initial public offering that was one of the worlds top five largest IPOs to date, and returned to profitability later that year. General Motors Corporation was formed on September 16,1908, in Flint, Michigan, GMs co-founder was Charles Stewart Mott, whose carriage company was merged into Buick prior to GMs creation. Over the years, Mott became the largest single stockholder in GM, and spent his life with his Mott Foundation, GM acquired Oldsmobile later that year. In 1909, Durant brought in Cadillac, Elmore, Oakland, also in 1909, GM acquired the Reliance Motor Truck Company of Owosso, Michigan, and the Rapid Motor Vehicle Company of Pontiac, Michigan, the predecessors of GMC Truck. Durant, along with R. S. McLaughlin, lost control of GM in 1910 to a bankers trust, because of the amount of debt taken on in its acquisitions. The next year, Durant started the Chevrolet Motor Car Company in the U. S. and in Canada in 1915, Durant took back control of the company after one of the most dramatic proxy wars in American business history. Durant then reorganized General Motors Company into General Motors Corporation in 1916, merging Chevrolet with GM, shortly thereafter, he again lost control, this time for good, after the new vehicle market collapsed. These facilities were added to the factories that were exclusive to Cadillac, Buick, Oldsmobile, Oakland

Opel Commodore
–
The Opel Commodore was an executive car produced by Opel from 1967 to 1982. It is the variant of the Rekord with styling differences. The Commodore nameplate was used by Opel from 1967 to 1982, however, its nameplate/lineage continues with the Australian Holden Commodore. The last generation was sold in the United Kingdom primarily as the Vauxhall Viceroy although Opel models were also sold, the Opel Commodore A was manufactured from 1967 to 1971, based on the Rekord C. After having offered a Rekord-6 powered by a 2.6 L 6-cylinder engine since March 1964, the Commodore was initially available with the known A2. 2-litre six or a larger 2.5 L engine developing 115 PS with a single carburettor. Body styles comprised a two-door or four-door notchback saloon and a two-door hardtop/fastback coupé, in September 1967 the sporty Commodore GS offering 130 hp from a double-carburettor 2.5 L-six was introduced. For model year 1969, the carryover 2. 2-litre six was dropped, the handbrake lever was moved from its position under the dash to a location between the front seats and the fuel tank was enlarged from 55 to 70 litres. An even more sporty model than the GS, the Commodore GS/E and it had a 2.5 L engine equipped with Bosch D-jetronic fuel injection system developing 150 PS, which gave the car a top speed of 197 km/h. The Commodore GS/E also had a career in motorsports, with a car prepared by Steinmetz, in April 1970 a Commodore with a detuned and carburetted 2.8 L-six giving 145 PS followed. 156,330 Commodore As were built, including 2,574 GS, the Commodore B was based on the Rekord D, and launched in 1972. As in the generation, four models were offered,2500 S,2500 GS,2800 GS and 2800 GS/E, as a four-door notchback saloon. Power ranged from 115 to 160 PS, the Rekord and Commodore were also assembled as CKD kits in Belgium and Switzerland in the 1970s. These cars carried the name Ranger and differed from the originals in having different grilles and these cars were exported to various countries. In 1974, due to new regulations regarding pollutant emissions, the 2.5 L base models were dropped, Commodore B production ended in 1977. The Commodore B series was like the A series briefly used in motorsports, and it used a 6. 0-litre V8 engine and had large wings which almost made it unrecognizable as an Opel. It never enjoyed much success despite of its massive powerplant and impressive output. Opel Commodores were also built in Iran between 1973 and 1976 under the name Chevrolet Iran or Chevrolet Royale 2800 and 2500 with both 2.5 L and 2.8 L engines by Iran General Motors Company. It was also assembled in South Africa, where it was called the Chevrolet 2500,3800, and 4100 and these received inline-four or -six engines of Chevrolet origins, built locally

Single-board computer
–
A single-board computer is a complete computer built on a single circuit board, with microprocessor, memory, input/output and other features required of a functional computer. Single-board computers were made as demonstration or development systems, for educational systems, many types of home computers or portable computers integrate all their functions onto a single printed circuit board. Unlike a desktop computer, single board computers often do not rely on expansion slots for peripheral functions or expansion. Single board computers have been using a wide range of microprocessors. Simple designs, such as built by hobbyists, often use static RAM. Other types, such as servers, would perform similar to a server computer. A computer-on-module is a type of single-board computer made to plug into a board, baseboard. The first true single-board computer called the dyna-micro was based on the Intel C8080A, and also used Intels first EPROM, the C1702A. The dyna-micro was re-branded by E&L Instruments of Derby, CT in 1976 as the MMD-1 and was famous as the example microcomputer in the very popular 8080 BugBook series of the time. SBCs also figured heavily in the history of home computers, for example in the Acorn Electron. Other typical early single board computers like the KIM-1 were often shipped without enclosure, which had to be added by the owner, other examples are the Ferguson Big Board, as the PC market became more prevalent, fewer SBCs were being used in computers. The main components were assembled on a motherboard, and peripheral components such as ports, disk drive controllers. Plug-in cards are now more commonly high performance graphics cards, high end RAID controllers, Single board computers were made possible by increasing density of integrated circuits. A single-board configuration reduces a systems overall cost, by reducing the number of circuit boards required, by putting all the functions on one board, a smaller overall system can be obtained, for example, as in notebook computers. Connectors are a frequent source of reliability problems, so a single-board system eliminates these problems, Single board computers are now commonly defined across two distinct architectures, no slots and slot support. Embedded SBCs are units providing all the required I/O with no provision for plug-in cards, applications are typically gaming, kiosk, and machine control automation. The term Single Board Computer now generally applies to an architecture where the board computer is plugged into a backplane to provide for I/O cards. In the case of PC104, the bus is not a backplane in the traditional sense but is a series of pin connectors allowing I/O boards to be stacked

QWERTY
–
QWERTY is a keyboard layout for Latin script. The name comes from the order of the first six keys on the top left letter row of the keyboard, the QWERTY design is based on a layout created for the Sholes and Glidden typewriter and sold to Remington in 1873. It became popular with the success of the Remington No, the QWERTY layout was devised and created in the early 1870s by Christopher Latham Sholes, a newspaper editor and printer who lived in Milwaukee, Wisconsin. In October 1867, Sholes filed a patent application for his writing machine he developed with the assistance of his friends Carlos Glidden. Firstly, characters were mounted on arms or typebars, which would clash. Secondly, its point was located beneath the paper carriage, invisible to the operator. Consequently, jams were especially serious, because the typist could only discover the mishap by raising the carriage to inspect what had been typed, the solution was to place commonly used letter-pairs so that their typebars were not neighboring, avoiding jams. Sholes struggled for the five years to perfect his invention. The study of bigram frequency by educator Amos Densmore, brother of the financial backer James Densmore, is believed to have influenced the arrangement of letters, others suggest instead that the letter arrangement evolved from telegraph operators feedback. In November 1868 he changed the arrangement of the half of the alphabet, O to Z. These adjustments included placing the R key in the previously allotted to the period key. Apocryphal claims that change was made to let salesmen impress customers by pecking out the brand name TYPE WRITER QUOTE from one keyboard row are not formally substantiated. Vestiges of the original layout remained in the home row sequence DFGHJKL. The modern layout is, The QWERTY layout became popular with the success of the Remington No.2 of 1878, the first typewriter to include both upper and lower case letters, using a shift key. 0 and 1 were omitted to simplify the design and reduce the manufacturing and maintenance costs, they were chosen specifically because they were redundant and could be recreated using other keys. Typists who learned on these machines learned the habit of using the uppercase letter I for the one. In early designs, some characters were produced by printing two symbols with the carriage in the same position. For instance, the point, which shares a key with the numeral 1 on modern keyboards, could be reproduced by using a three-stroke combination of an apostrophe, a backspace

Monochrome
–
Monochrome describes paintings, drawings, design, or photographs in one color or values of one color. A monochromatic object or image reflects colors in shades of limited colors or hues, images using only shades of grey are called grayscale or black-and-white. However, scientifically speaking, monochromatic light refers to light of a narrow band of wavelengths. In computing, monochrome has two meanings, it may mean having only one color which is either on or off, a monochrome computer display is able to display only a single color, often green, amber, red or white, and often also shades of that color. In film photography, monochrome is typically the use of black-and-white film, originally, all photography was done in monochrome. Although color photography was possible even in the late 19th century, easily used color films, if the red channel is eliminated and the green and blue combined then the effect will be similar to that of orthochromatic film or the use of a cyan filter on panchromatic film. The selection of weighting thus allows a range of artistic expression in the final monochromatic image. For production of an image the original color stereogram source may first be reduced to monochrome in order to simplify the rendering of the image. This is sometimes required in cases where an image would render in a confusing manner given the colors and patterns present in the source image. In physics, monochromatic light is electromagnetic radiation of a single frequency, even very controlled sources such as lasers operate in a range of frequencies. In practice, filtered light, diffraction grating separated light and laser light are all referred to as monochromatic. Often light sources can be compared and one be labeled as “more monochromatic”

Computer monitor
–
A computer monitor or a computer display is an electronic visual display for computers. A monitor usually comprises the display device, circuitry, casing, the display device in modern monitors is typically a thin film transistor liquid crystal display or a flat panel LED display, while older monitors used a cathode ray tubes. It can be connected to the computer via VGA, DVI, HDMI, DisplayPort, Thunderbolt, LVDS or other proprietary connectors, originally, computer monitors were used for data processing while television receivers were used for entertainment. From the 1980s onwards, computers have used for both data processing and entertainment, while televisions have implemented some computer functionality. The common aspect ratio of televisions, and computer monitors, has changed from 4,3 to 16,10, to 16,9. Early electronic computers were fitted with a panel of light bulbs where the state of each particular bulb would indicate the state of a particular register bit inside the computer. This allowed the operating the computer to monitor the internal state of the machine. As early monitors were only capable of displaying a limited amount of information. Instead, a printer was the primary output device, while the monitor was limited to keeping track of the programs operation. Multiple technologies have used for computer monitors. Until the 21st century most used cathode ray tubes but they have largely superseded by LCD monitors. The first computer monitors used cathode ray tubes, high-resolution CRT displays were developed for specialized military, industrial and scientific applications but they were far too costly for general use. Either computer could be connected to the terminals of an ordinary color TV set or used with a purpose-made CRT color monitor for optimum resolution. In 1984 IBM introduced the Enhanced Graphics Adapter which was capable of producing 16 colors and had a resolution of 640 x 350, by the end of the 1980s color CRT monitors that could clearly display 1024 x 768 pixels were widely available and increasingly affordable. During the following decade maximum display resolutions gradually increased and prices continued to fall, CRT technology remained dominant in the PC monitor market into the new millennium partly because it was cheaper to produce and offered viewing angles close to 180 degrees. CRTs still offer some image quality advantages over LCDs but improvements to the latter have made much less obvious. There are multiple technologies that have used to implement liquid crystal displays. Commonly, the laptop would be offered with an assortment of display options at increasing price points, monochrome

Commodore Datasette
–
The Commodore 1530 Datasette was Commodores dedicated magnetic tape data storage device. Using compact cassettes as the medium, it provided inexpensive storage to Commodores 8-bit home/personal computers, notably the PET, VIC-20. A physically similar model, Commodore 1531, was made for the Commodore 16, unlike most microcomputer storage methods using compact cassettes, the Datasette uses a digital format. Instead of writing two tones to tape to indicate bits, patterns of waves are used including a parity bit. Programs are written twice to tape for error correction, if an error is detected when reading the first recording, the Datasette has built-in analog to digital converters and audio filters to convert the computers digital data into analog sound and vice versa. Connection to the computer is done via an edge connector or mini-DIN connector. The Datasette was more popular outside than inside the United States, in the United States disk drives quickly became standard, despite the Commodore 1541 floppy drive costing roughly five times as much as a Datasette. In most parts of Europe, the Datasette was the medium of choice for years after its launch. The inexpensive and widely available audio cassettes made the Datasette a good choice for the home computer mass market. The Datasette is slow—but because of its digital format extremely reliable—transferring data at around 50 bytes per second, after the Datasettes launch, however, special turbo tape software appeared, providing much faster tape operation. Such software was integrated into most commercial prerecorded applications, as well as being available separately for loading and saving the users homemade programs and these programs were only widely used in Europe, as the US market had long since moved onto disks. Datasettes can typically store about 100 kByte per 30 minute side, the use of turbo tape and other fast loaders increased this number to roughly 1000 kByte. The Datasette has only one cable with a PCB edge connector at the computer end. All input/output signals to the datasette are all digital and so all digital to analog, power is also included in this cable. The pinout is ground, +5 V DC, motor, read, write, the sense signal monitors the play, rewind, and fast-forward buttons, but cannot differentiate between them. A mechanical interlock prevented any two of them being pressed at the same time, unregulated 6.36 V DC is used to power the cassette motor. To record physical data, the zero-crossing from positive to negative voltage of the signal is measured. The resulting time between these positive to negative crossings is then compared to a threshold to determine whether the time since the last crossing is short or long, note the lower amplitude for the shorter periods

The Bahamas
–
The Bahamas, known officially as the Commonwealth of the Bahamas, is an archipelagic state within the Lucayan Archipelago. The capital is Nassau on the island of New Providence, the designation of the Bahamas can refer either to the country or to the larger island chain that it shares with the Turks and Caicos Islands. As stated in the mandate/manifesto of the Royal Bahamas Defence Force, the Bahamas is the site of Columbus first landfall in the New World in 1492. At that time, the islands were inhabited by the Lucayan, although the Spanish never colonised the Bahamas, they shipped the native Lucayans to slavery in Hispaniola. The islands were mostly deserted from 1513 until 1648, when English colonists from Bermuda settled on the island of Eleuthera, the Bahamas became a British Crown colony in 1718, when the British clamped down on piracy. After the American War of Independence, the Crown resettled thousands of American Loyalists in the Bahamas, they brought their slaves with them, Africans constituted the majority of the population from this period. Slavery in the Bahamas was abolished in 1834, Today the descendants of slaves and free Africans make up nearly 90% of the population, issues related to the slavery years are part of society. The Bahamas became an independent Commonwealth realm in 1973, retaining Queen Elizabeth II as its monarch, in terms of gross domestic product per capita, the Bahamas is one of the richest countries in the Americas, with an economy based on tourism and finance. The name Bahamas is derived from either the Taino ba ha ma, alternatively, it may originate from Guanahani, a local name of unclear meaning. In English, the Bahamas is one of two countries whose self-standing short name begins with the word the, along with The Gambia. Taino people moved into the uninhabited southern Bahamas from Hispaniola and Cuba around the 11th century and they came to be known as the Lucayan people. An estimated 30,000 Lucayan inhabited the Bahamas at the time of Christopher Columbus arrival in 1492, Columbuss first landfall in the New World was on an island he named San Salvador. Some researchers believe this site to be present-day San Salvador Island, an alternative theory holds that Columbus landed to the southeast on Samana Cay, according to calculations made in 1986 by National Geographic writer and editor Joseph Judge, based on Columbuss log. Evidence in support of this remains inconclusive, on the landfall island, Columbus made first contact with the Lucayan and exchanged goods with them. The Spanish forced much of the Lucayan population to Hispaniola for use as forced labour, the slaves suffered from harsh conditions and most died from contracting diseases to which they had no immunity, half of the Taino died from smallpox alone. The population of the Bahamas was severely diminished, in 1648, the Eleutherian Adventurers, led by William Sayle, migrated from Bermuda. These English Puritans established the first permanent European settlement on an island which they named Eleuthera—the name derives from the Greek word for freedom and they later settled New Providence, naming it Sayles Island after one of their leaders. To survive, the settlers salvaged goods from wrecks, in 1670 King Charles II granted the islands to the Lords Proprietors of the Carolinas in North America

Braunschweig
–
Braunschweig, also called Brunswick in English, is a city of 252,768 people, in the state of Lower Saxony, Germany. It is located north of the Harz mountains at the furthest navigable point of the Oker river, today, Braunschweig is the second largest city in Lower Saxony and a major centre of scientific research and development. The date and circumstances of the foundation are unknown. The towns original name of Brunswik is a combination of the name Bruno and Low German wik, the towns name therefore indicates an ideal resting-place, as it lay by a ford across the Oker River. Another explanation of the name is that it comes from Brand. The city was first mentioned in documents from the St. Magni Church from 1031, up to the 12th century, Braunschweig was ruled by the Saxon noble family of the Brunonids, then, through marriage, it fell to the House of Welf. In 1142 Henry the Lion of the House of Welf became duke of Saxony and he turned Dankwarderode Castle, the residence of the counts of Brunswick, into his own Pfalz and developed the city further to represent his authority. Under Henrys rule the Cathedral of St. Blasius was built and he also had the statue of a lion, his heraldic animal, the lion subsequently became the citys landmark. Henry the Lion became so powerful that he dared to refuse military aid to the emperor Frederick I Barbarossa, Henry went into exile in England. He had previously established ties to the English crown in 1168, through his marriage to King Henry II of Englands daughter Matilda, however, his son Otto, who could regain influence and was eventually crowned Holy Roman Emperor, continued to foster the citys development. By the year 1600, Braunschweig was the seventh largest city in Germany, the Princes of Brunswick-Wolfenbüttel didnt regain control over the city until the late 17th century, when Rudolph Augustus, Duke of Brunswick-Lüneburg, took the city by siege. In the 18th century Braunschweig was not only a political, influenced by the philosophy of the Enlightenment, dukes like Anthony Ulrich and Charles I became patrons of the arts and sciences. In 1745 Charles I founded the Collegium Carolinum, predecessor of the Braunschweig University of Technology, with this he attracted poets and thinkers such as Lessing, Leisewitz, and Jakob Mauvillon to his court and the city. Emilia Galotti by Lessing and Goethes Faust were performed for the first time in Braunschweig, in 1806, the city was captured by the French during the Napoleonic Wars and became part of the short-lived Napoleonic Kingdom of Westphalia in 1807. The exiled duke Frederick William raised a corps, the Black Brunswickers. After the Congress of Vienna in 1815, Braunschweig was made capital of the reestablished independent Duchy of Brunswick, in the aftermath of the July Revolution in 1830, in Brunswick duke Charles II was forced to abdicate. His absolutist governing style had alienated the nobility and bourgeoisie. During the night of 7–8 September 1830, the palace in Braunschweig was stormed by an angry mob, set on fire

Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe. It includes 16 constituent states, covers an area of 357,021 square kilometres, with about 82 million inhabitants, Germany is the most populous member state of the European Union. After the United States, it is the second most popular destination in the world. Germanys capital and largest metropolis is Berlin, while its largest conurbation is the Ruhr, other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart, Düsseldorf and Leipzig. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity, a region named Germania was documented before 100 AD. During the Migration Period the Germanic tribes expanded southward, beginning in the 10th century, German territories formed a central part of the Holy Roman Empire. During the 16th century, northern German regions became the centre of the Protestant Reformation, in 1871, Germany became a nation state when most of the German states unified into the Prussian-dominated German Empire. After World War I and the German Revolution of 1918–1919, the Empire was replaced by the parliamentary Weimar Republic, the establishment of the national socialist dictatorship in 1933 led to World War II and the Holocaust. After a period of Allied occupation, two German states were founded, the Federal Republic of Germany and the German Democratic Republic, in 1990, the country was reunified. In the 21st century, Germany is a power and has the worlds fourth-largest economy by nominal GDP. As a global leader in industrial and technological sectors, it is both the worlds third-largest exporter and importer of goods. Germany is a country with a very high standard of living sustained by a skilled. It upholds a social security and universal health system, environmental protection. Germany was a member of the European Economic Community in 1957. It is part of the Schengen Area, and became a co-founder of the Eurozone in 1999, Germany is a member of the United Nations, NATO, the G8, the G20, and the OECD. The national military expenditure is the 9th highest in the world, the English word Germany derives from the Latin Germania, which came into use after Julius Caesar adopted it for the peoples east of the Rhine. This in turn descends from Proto-Germanic *þiudiskaz popular, derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- people, the discovery of the Mauer 1 mandible shows that ancient humans were present in Germany at least 600,000 years ago. The oldest complete hunting weapons found anywhere in the world were discovered in a mine in Schöningen where three 380, 000-year-old wooden javelins were unearthed

European Economic Community
–
The European Economic Community was a regional organisation which aimed to bring about economic integration among its member states. It was created by the Treaty of Rome of 1957, upon the formation of the European Union in 1993, the EEC was incorporated and renamed as the European Community. In 2009 the ECs institutions were absorbed into the EUs wider framework and it gained a common set of institutions along with the European Coal and Steel Community and the European Atomic Energy Community as one of the European Communities under the 1965 Merger Treaty. In 1993, a single market was achieved, known as the internal market, which allowed for the free movement of goods, capital, services. In 1994, the market was formalised by the EEA agreement. This agreement also extended the market to include most of the member states of the European Free Trade Association. Upon the entry into force of the Maastricht Treaty in 1993 and this was also when the three European Communities, including the EC, were collectively made to constitute the first of the three pillars of the European Union, which the treaty also founded. The EEC was also known as the Common Market in the English-speaking countries and sometimes referred to as the European Community even before it was renamed as such in 1993. In 1951, the Treaty of Paris was signed, creating the European Coal and this was an international community based on supranationalism and international law, designed to help the economy of Europe and prevent future war by integrating its members. In the aim of creating a federal Europe two further communities were proposed, a European Defence Community and a European Political Community. While the treaty for the latter was being drawn up by the Common Assembly, the ECSC parliamentary chamber, after the Messina Conference in 1955, Paul Henri Spaak was given the task to prepare a report on the idea of a customs union. The so-called Spaak Report of the Spaak Committee formed the cornerstone of the negotiations at Val Duchesse castle in 1956. Together with the Ohlin Report the Spaak Report would provide the basis for the Treaty of Rome, in 1956, Paul Henri Spaak led the Intergovernmental Conference on the Common Market and Euratom at the Val Duchesse castle, which prepared for the Treaty of Rome in 1957. The conference led to the signature, on 25 March 1957, the resulting communities were the European Economic Community and the European Atomic Energy Community. These were markedly less supranational than the communities, due to protests from some countries that their sovereignty was being infringed. The first formal meeting of the Hallstein Commission, was held on 16 January 1958 at the Chateau de Val-Duchesse, the EEC was to create a customs union while Euratom would promote co-operation in the nuclear power sphere. The EEC rapidly became the most important of these and expanded its activities, one of the first important accomplishments of the EEC was the establishment of common price levels for agricultural products. In 1968, internal tariffs were removed on certain products, another crisis was triggered in regard to proposals for the financing of the Common Agricultural Policy, which came into force in 1962

Local area network
–
By contrast, a wide area network, not only covers a larger geographic distance, but also generally involves leased telecommunication circuits or Internet links. An even greater contrast is the Internet, which is a system of globally connected business, Ethernet and Wi-Fi are the two most common transmission technologies in use for local area networks. Historical technologies include ARCNET, Token ring, and AppleTalk, the increasing demand and use of computers in universities and research labs in the late 1960s generated the need to provide high-speed interconnections between computer systems. A1970 report from the Lawrence Radiation Laboratory detailing the growth of their Octopus network gave an indication of the situation. A number of experimental and early commercial LAN technologies were developed in the 1970s, Cambridge Ring was developed at Cambridge University starting in 1974. Ethernet was developed at Xerox PARC in 1973–1975, and filed as U. S, in 1976, after the system was deployed at PARC, Robert Metcalfe and David Boggs published a seminal paper, Ethernet, Distributed Packet-Switching for Local Computer Networks. ARCNET was developed by Datapoint Corporation in 1976 and announced in 1977 and it had the first commercial installation in December 1977 at Chase Manhattan Bank in New York. The initial driving force for networking was generally to share storage and printers, there was much enthusiasm for the concept and for several years, from about 1983 onward, computer industry pundits would regularly declare the coming year to be, “The year of the LAN”. In practice, the concept was marred by proliferation of incompatible physical layer and network protocol implementations, typically, each vendor would have its own type of network card, cabling, protocol, and network operating system. Netware dominated the personal computer LAN business from early after its introduction in 1983 until the mid-1990s when Microsoft introduced Windows NT Advanced Server, of the competitors to NetWare, only Banyan Vines had comparable technical strengths, but Banyan never gained a secure base. During the same period, Unix workstations were using TCP/IP networking, early LAN cabling had generally been based on various grades of coaxial cable. This led to the development of 10BASE-T and structured cabling which is still the basis of most commercial LANs today, while fiber-optic cabling is common for links between switches, use of fiber to the desktop is rare. Many LANs use wireless technologies that are built into Smartphones, tablet computers, in a wireless local area network, users may move unrestricted in the coverage area. Wireless networks have become popular in residences and small businesses, because of their ease of installation, guests are often offered Internet access via a hotspot service. Network topology describes the layout of interconnections between devices and network segments, at the data link layer and physical layer, a wide variety of LAN topologies have been used, including ring, bus, mesh and star. At the higher layers, NetBEUI, IPX/SPX, AppleTalk and others were once common, simple LANs generally consist of cabling and one or more switches. A switch can be connected to a router, cable modem, a LAN can include a wide variety of other network devices such as firewalls, load balancers, and network intrusion detection. LANs can maintain connections with other LANs via leased lines, leased services, depending on how the connections are established and secured, and the distance involved, such linked LANs may also be classified as a metropolitan area network or a wide area network

William Shatner
–
William Shatner is a Canadian actor, author, producer, and director. In his seven decades of television, Shatner became an icon for his portrayal of James T. Kirk, Captain of the USS Enterprise. He has written a series of books chronicling his experiences playing Captain Kirk and being a part of Star Trek and he has written a series of science fiction novels called TekWar, which were adapted for television. Shatner also appeared in the NBC series, 3rd Rock from the Sun in seasons 4 and 5 as the role of the Big Giant Head whom the characters of the Series reported to. He has worked as a musician, an author, a director, and he starred as attorney Denny Crane in the final season of the legal drama The Practice and its spinoff series Boston Legal, a role that earned him two Emmy Awards. Shatner was born on March 22,1931, in the Notre-Dame-de-Grâce neighbourhood of Montreal, Quebec, Canada, the son of Anne and Joseph Shatner and he has two sisters, Joy and Farla. His paternal grandfather, Wolf Schattner, anglicized the name to Shatner. All of Shatners grandparents were Jewish immigrants, and he was raised in Conservative Judaism, Shatner attended two schools in Notre-Dame-de-Grâce, Willingdon Elementary School and Westhill High School, and is an alumnus of the Montreal Childrens Theatre. He studied Economics at the McGill University Faculty of Management in Montreal, Canada, in June 2011, McGill University awarded him an honorary Doctorate of Letters. Shatner began performing at the Stratford Shakespeare Festival in Stratford, Ontario, in 1954, he was cast as Ranger Bob on The Canadian Howdy Doody Show. Shatner was an understudy to Christopher Plummer, the two would appear as adversaries in Star Trek VI, The Undiscovered Country. Shatner had a role in an Alfred Hitchcock Presents third-season episode titled The Glass Eye. In 1959, he received good reviews when he played the role of Lomax in the Broadway production of The World of Suzie Wong. He appeared twice as Wayne Gorham in NBCs Outlaws Western series with Barton MacLane, in 1961, he starred in the Broadway play A Shot in the Dark with Julie Harris and directed by Harold Clurman. Walter Matthau and Gene Saks were also featured in this play, Shatner featured in two episodes of the NBC television series Thriller and the film The Explosive Generation. Guthrie had called the young Shatner the Stratford Festivals most promising actor, Shatner was not as successful as the others, however, and during the 1960s he became a working actor who showed up on time, knew his lines, worked cheap and always answered his phone. His motto was Work equals work, but Shatners willingness to take any role, no matter how forgettable, in the 1963–1964 season, he appeared in episodes of two ABC series, Channing and The Outer Limits. In 1963, he starred in the Family Theater production called The Soldier and that same year, he guest starred in Route 66, in the episode, Build Your Houses with Their Backs to the Sea

Integrated circuit
–
An integrated circuit or monolithic integrated circuit is a set of electronic circuits on one small flat piece of semiconductor material, normally silicon. The ICs mass production capability, reliability and building-block approach to circuit design ensured the rapid adoption of standardized ICs in place of using discrete transistors. ICs are now used in all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones, and other home appliances are now inextricable parts of the structure of modern societies, made possible by the small size. These advances, roughly following Moores law, allow a computer chip of 2016 to have millions of times the capacity, ICs have two main advantages over discrete circuits, cost and performance. Cost is low because the chips, with all their components, are printed as a unit by photolithography rather than being constructed one transistor at a time, furthermore, packaged ICs use much less material than discrete circuits. Performance is high because the ICs components switch quickly and consume little power because of their small size, the main disadvantage of ICs is the high cost to design them and fabricate the required photomasks. This high initial cost means ICs are only practical when high production volumes are anticipated, Circuits meeting this definition can be constructed using many different technologies, including thin-film transistor, thick film technology, or hybrid integrated circuit. However, in general usage integrated circuit has come to refer to the single-piece circuit construction originally known as a integrated circuit. Jacobi disclosed small and cheap hearing aids as typical industrial applications of his patent, an immediate commercial use of his patent has not been reported. The idea of the circuit was conceived by Geoffrey Dummer. Dummer presented the idea to the public at the Symposium on Progress in Quality Electronic Components in Washington and he gave many symposia publicly to propagate his ideas, and unsuccessfully attempted to build such a circuit in 1956. A precursor idea to the IC was to create small ceramic squares, Components could then be integrated and wired into a bidimensional or tridimensional compact grid. This idea, which seemed very promising in 1957, was proposed to the US Army by Jack Kilby, however, as the project was gaining momentum, Kilby came up with a new, revolutionary design, the IC. In his patent application of 6 February 1959, Kilby described his new device as a body of semiconductor material … wherein all the components of the circuit are completely integrated. The first customer for the new invention was the US Air Force, Kilby won the 2000 Nobel Prize in Physics for his part in the invention of the integrated circuit. His work was named an IEEE Milestone in 2009, half a year after Kilby, Robert Noyce at Fairchild Semiconductor developed his own idea of an integrated circuit that solved many practical problems Kilbys had not. Noyces design was made of silicon, whereas Kilbys chip was made of germanium, Noyce credited Kurt Lehovec of Sprague Electric for the principle of p–n junction isolation, a key concept behind the IC

Demoscene
–
A compo is a contest relating to programming, computer graphics and music that takes place within the demoscene and related subcultures. The term compo is a shortening of competition, compos are typically held at demoparties. The usual format is to show the competing entries sequentially with a video projector, in addition to party-based contests, there have also been online compos on websites and bulletin board systems. The main competition on most demoparties is the demo compo, a typical party also includes an intro compo, a music compo and a graphics compo. Other common contests include wild compo and game development compo, compos are often split into subcategories by technical and stylistic restrictions. Compos at a demoparty are usually held during the afternoon and lasting after midnight, each compo has its designated deadline, to which the competitors must deliver their entries, either via traditional physical media or through the party LAN. The crew also performs preselection on the entries to be able to fit in a given timeframe with the competition, and also to maintain a quality level for a given competition. Compos show the production in an order, some parties prefer to reorder competition entries in an ascending order quality-wise. At some parties, individual competitions omit the display of the name at this point. After the compo, visitors are given the opportunity to vote, to avoid mass-votes by individuals, a votesheet or votekey is usually only handed out to a visitor in exchange of a mark on the ticket, such as tickmark or the removal of the wristband. Votes, usually done via either preferential voting or range voting, are calculated after the voting deadline, fastcompos are a common form of entertainment at demoparties. Unlike regular compos, fastcompos are announced at the party, usually only a few hours to a day before the deadline, fastcompos may be held for music, graphics, demos and anything else regular compos are

History of personal computers
–
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1980s. The 1981 launch of the IBM Personal Computer coined both the term Personal Computer and PC, after the development of the microprocessor, individual personal computers were low enough in cost that they eventually became affordable consumer goods. Early personal computers – generally called microcomputers – were sold often in electronic kit form and in limited numbers, mauchly stated, There is no reason to suppose the average boy or girl cannot be master of a personal computer. In 1968, a manufacturer took the risk of referring to their product this way and this advertisement was deemed too extreme for the target audience and replaced with a much drier ad for the HP 9100A programmable calculator. In 1977, three new pre-assembled small computers hit the markets which Byte would refer to as the 1977 Trinity of personal computing. The Apple II and the PET2001 were advertised as personal computers, by 1979, over half a million microcomputers were sold and the youth of the day had a new concept of the personal computer. After the development of the microprocessor, individual computers were low enough in cost that they eventually became affordable consumer goods. Early personal computers – generally called microcomputers– were sold often in electronic kit form and in limited numbers, Computer terminals were used for time sharing access to central computers. End users generally did not directly interact with the machine, but instead would prepare tasks for the computer on off-line equipment, a number of assignments for the computer would be gathered up and processed in batch mode. After the job had completed, users could collect the results, in some cases, it could take hours or days between submitting a job to the computing center and receiving the output. A more interactive form of computer use developed commercially by the middle 1960s, in a time-sharing system, multiple computer terminals let many people share the use of one mainframe computer processor. This was common in applications and in science and engineering. A different model of use was foreshadowed by the way in which early, pre-commercial, experimental computers were used. By todays standards, they were large and cost prohibitive. However, they were smaller, less expensive, and generally simpler to operate than many of the mainframe computers of the time. Therefore, they were accessible for individual laboratories and research projects, minicomputers largely freed these organizations from the batch processing and bureaucracy of a commercial or university computing center. In addition, minicomputers were relatively interactive and soon had their own operating systems, in 1945, Vannevar Bush published an essay called As We May Think in which he outlined a possible solution to the growing problem of information storage and retrieval. The demo was the culmination of research in Engelbarts Augmentation Research Center laboratory, the minicomputer ancestors of the modern personal computer used early integrated circuit technology, which reduced size and cost, but they contained no microprocessor

Texas Instruments TI-99/4A
–
The Texas Instruments TI-99/4A is a home computer, released June 1981 in the United States at a price of $525. It is a version of the less successful TI-99/4 model. The TI-99/4 has a calculator-style chiclet keyboard and a set that lacked lowercase text. The TI-99/4A added an additional graphics mode, lowercase characters consisting of capitals. Both use 16-bit processors, making the TI-99/4 series the first 16-bit home computers, the TI-99/4As CPU, motherboard, and ROM cartridge slot are built into the keyboard. The power regulator board is housed below and in front of the cartridge slot under the area to the right of the keyboard. This area gets very hot so users commonly refer to it as the coffee cup warmer, the external power supply, which was different according to the country of sale, is a step-down transformer. The TI-99/4 was sold both the computer and a monitor as Texas Instruments could not get its RF modulator approved by the U. S. Federal Communications Commission in time. The TI-99/4A did ship with an RF modulator, in the early 1980s, TI was known as a pioneer in speech synthesis, and a highly popular plug-in speech synthesizer module was available for the TI-99/4 and 4A. Speech synthesizers were offered free with the purchase of a number of cartridges and were used by many TI-written video games, the synthesizer uses a variant of linear predictive coding and has a small in-built vocabulary. The original intent was to release small cartridges that plugged directly into the synthesizer unit, however, the success of software text-to-speech in the Terminal Emulator II cartridge cancelled that plan. In many games, the synthesizer has relatively realistic voices. For example, Alpiners speech includes male and female voices and can be quite sarcastic when the player made a bad move, the TI-99/4s original expansion concept was that peripherals would be connected serially to the console and each other, in a daisy-chain fashion. This original idea was replaced by a system based on expansion cards. Each card also has its own light, an LED which would blink or flicker when the card was being used by software. As on the earlier S-100 bus, the section of the supply that power the card slots is unregulated. The PEB also carries an analog sound input on the expansion bus and this allows the TI Speech Synthesizers audio to be carried through the console to the monitor. No official cards from Texas Instruments ever made use of this line, early models includes a built-in equation calculator, but in the 99/4A this feature was discontinued

Atari
–
Atari is a corporate and brand name owned by several entities since its inception in 1972, currently by Atari Interactive, a subsidiary of the French publisher Atari, SA. The original Atari, Inc. founded in 1972 by Nolan Bushnell and Ted Dabney was a pioneer in arcade games, home game consoles. The companys products, such as Pong and the Atari 2600, in 1984, the original Atari Inc. was split due to its role in the video game crash of 1983, and the arcade division was turned into Atari Games Inc. Atari Games received the rights to use the logo and brand name with appended text Games on arcade games, the Atari Consumer Electronics Division properties were in turn sold to Jack Tramiels Tramel Technology Ltd. which then renamed itself to Atari Corporation. In 1996, Atari Corporation reverse-merged with disk-drive manufacturer JT Storage, in 1998,6 November Hasbro Interactive acquired all Atari Corporation related properties from JTS, creating a new subsidiary, Atari Interactive. After IESAs acquisition of Hasbro Interactive, Infogrames, Inc. intermittently published Atari branded titles for Infogrames Interactive, on October 11,2008, Infogrames completed its acquisition of Atari, Inc. making it a wholly owned subsidiary. In 1971, Nolan Bushnell and Ted Dabney founded a firm, Syzygy Engineering, that designed and built Computer Space. On June 27,1972 Atari, Inc. was incorporated, Bushnell asked Alcorn produce an arcade version of the Magnavox Odysseys Tennis game, which would be named Pong. While Bushnell incorporated Atari in June 1972, Syzygy Company was never formally incorporated, Atari was incorporated in the state of California on June 27,1972. Joe Keenans management of the led to him being promoted president of Atari that same year. In 1976, Bushnell, through Grass Valley, CA firm Cyan Engineering, the result was the Atari Video Computer System, or VCS. The introductory price of $199 included a console, two joysticks, a pair of paddles, and the Combat game cartridge, Bushnell knew he had another potential hit on his hands but bringing the machine to market would be extremely expensive. Looking for outside investors, Bushnell sold Atari to Warner Communications in 1976 for an estimated $28–32 million, Nolan continued to have disagreements with Warner Management over the direction of the company, the discontinuation of the pinball division, and most important, the notion of discontinuing the 2600. In 1978, Kee Games was disbanded, in December of that year, Nolan Bushnell was fired following an argument with Manny Gerard. E started fighting like cats and dogs, and then the wheels came off that fall. Warner claimed they fired me, recalled Bushnell, development of a successor to the 2600 started as soon as it shipped. The original team estimated the 2600 had a lifespan of three years, it then set forth to build the most powerful machine possible within that time frame. Mid-way into their effort the home computer revolution took off, leading to the addition of a keyboard and features to produce the Atari 800 and its smaller sibling, the new machines had some success when they finally became available in quantity in 1980

Apple Inc.
–
Apple is an American multinational technology company headquartered in Cupertino, California that designs, develops, and sells consumer electronics, computer software, and online services. Apples consumer software includes the macOS and iOS operating systems, the media player, the Safari web browser. Its online services include the iTunes Store, the iOS App Store and Mac App Store, Apple Music, Apple was founded by Steve Jobs, Steve Wozniak, and Ronald Wayne in April 1976 to develop and sell personal computers. It was incorporated as Apple Computer, Inc. in January 1977, Apple joined the Dow Jones Industrial Average in March 2015. In November 2014, Apple became the first U. S. company to be valued at over US$700 billion in addition to being the largest publicly traded corporation in the world by market capitalization. The company employs 115,000 full-time employees as of July 2015 and it operates the online Apple Store and iTunes Store, the latter of which is the worlds largest music retailer. Consumers use more than one billion Apple products worldwide as of March 2016, Apples worldwide annual revenue totaled $233 billion for the fiscal year ending in September 2015. This revenue accounts for approximately 1. 25% of the total United States GDP.1 billion, the corporation receives significant criticism regarding the labor practices of its contractors and its environmental and business practices, including the origins of source materials. Apple was founded on April 1,1976, by Steve Jobs, Steve Wozniak, the Apple I kits were computers single-handedly designed and hand-built by Wozniak and first shown to the public at the Homebrew Computer Club. The Apple I was sold as a motherboard, which was less than what is now considered a personal computer. The Apple I went on sale in July 1976 and was market-priced at $666.66, Apple was incorporated January 3,1977, without Wayne, who sold his share of the company back to Jobs and Wozniak for $800. Multimillionaire Mike Markkula provided essential business expertise and funding of $250,000 during the incorporation of Apple, during the first five years of operations revenues grew exponentially, doubling about every four months. Between September 1977 and September 1980 yearly sales grew from $775,000 to $118m, the Apple II, also invented by Wozniak, was introduced on April 16,1977, at the first West Coast Computer Faire. It differed from its rivals, the TRS-80 and Commodore PET, because of its character cell-based color graphics. While early Apple II models used ordinary cassette tapes as storage devices, they were superseded by the introduction of a 5 1/4 inch floppy disk drive and interface called the Disk II. The Apple II was chosen to be the platform for the first killer app of the business world, VisiCalc. VisiCalc created a market for the Apple II and gave home users an additional reason to buy an Apple II. Before VisiCalc, Apple had been a distant third place competitor to Commodore, by the end of the 1970s, Apple had a staff of computer designers and a production line
