Gasoline, gas or petrol is a colorless petroleum-derived flammable liquid, used as a fuel in spark-ignited internal combustion engines. It consists of organic compounds obtained by the fractional distillation of petroleum, enhanced with a variety of additives. On average, a 42-U. S.-gallon barrel of crude oil yields about 19 U. S. gallons of gasoline after processing in an oil refinery, though this varies based on the crude oil assay. The characteristic of a particular gasoline blend to resist igniting too early is measured by its octane rating. Gasoline is produced in several grades of octane rating. Tetraethyl lead and other lead compounds are no longer used in most areas to increase octane rating. Other chemicals are added to gasoline to improve chemical stability and performance characteristics, control corrosiveness and provide fuel system cleaning. Gasoline may contain oxygen-containing chemicals such as ethanol, MTBE or ETBE to improve combustion. Gasoline used in internal combustion engines can have significant effects on the local environment, is a contributor to global human carbon dioxide emissions.
Gasoline can enter the environment uncombusted, both as liquid and as vapor, from leakage and handling during production and delivery. As an example of efforts to control such leakage, many underground storage tanks are required to have extensive measures in place to detect and prevent such leaks. Gasoline contains other known carcinogens. "Gasoline" is a North American word. The Oxford English Dictionary dates its first recorded use to 1863 when it was spelled "gasolene"; the term "gasoline" was first used in North America in 1864. The word is a derivation from the word "gas" and the chemical suffixes "-ol" and "-ine" or "-ene". However, the term may have been influenced by the trademark "Cazeline" or "Gazeline". On 27 November 1862, the British publisher, coffee merchant and social campaigner John Cassell placed an advertisement in The Times of London: The Patent Cazeline Oil, safe and brilliant … possesses all the requisites which have so long been desired as a means of powerful artificial light.
This is the earliest occurrence of the word to have been found. Cassell discovered that a shopkeeper in Dublin named Samuel Boyd was selling counterfeit cazeline and wrote to him to ask him to stop. Boyd did not reply and changed every ‘C’ into a ‘G’, thus coining the word "gazeline"; the name "petrol" is used in place of "gasoline" in most Commonwealth countries. "Petrol" was first used as the name of a refined petroleum product around 1870 by British wholesaler Carless, Capel & Leonard, who marketed it as a solvent. When the product found a new use as a motor fuel, Frederick Simms, an associate of Gottlieb Daimler, suggested to Carless that they register the trademark "petrol", but by this time the word was in general use inspired by the French pétrole, the registration was not allowed. Carless registered a number of alternative names for the product, but "petrol" nonetheless became the common term for the fuel in the British Commonwealth. British refiners used "motor spirit" as a generic name for the automotive fuel and "aviation spirit" for aviation gasoline.
When Carless was denied a trademark on "petrol" in the 1930s, its competitors switched to the more popular name "petrol". However, "motor spirit" had made its way into laws and regulations, so the term remains in use as a formal name for petrol; the term is used most in Nigeria, where the largest petroleum companies call their product "premium motor spirit". Although "petrol" has made inroads into Nigerian English, "premium motor spirit" remains the formal name, used in scientific publications, government reports, newspapers; the use of the word gasoline instead of petrol outside North America can be confusing. Shortening gasoline to gas, which happens causes confusion with various forms of gaseous products used as automotive fuel like compressed natural gas, liquefied natural gas and liquefied petroleum gas ). In many languages, the name is derived from benzene, such as Benzin in benzina in Italian. Argentina and Paraguay use the colloquial name nafta derived from that of the chemical naphtha.
The first internal combustion engines suitable for use in transportation applications, so-called Otto engines, were developed in Germany during the last quarter of the 19th century. The fuel for these early engines was a volatile hydrocarbon obtained from coal gas. With a boiling point near 85 °C, it was well-suited for early carburetors; the development of a "spray nozzle" carburetor enabled the use of less volatile fuels. Further improvements in engine efficiency were attempted at higher compression ratios, but early attempts were blocked by the premature explosion of fuel, known as knocking. In 1891, the Shukhov cracking process became the world's first commercial method to break down heavier hydrocarbons in crude oil to increase the percentage of lighter products compared to simple distillation; the evolution of gasoline followed the evolution of oil as the dominant source of energy in the industrializing world. Prior to World War One, Britain was the world's greatest industrial power and depended on its navy to protect the shipping of raw materials from its colonies.
Germany was industrializing and, like Britain, lacked many natural resources which had to be shipped to the home country. By the 1890s, Germany
The PC-9800 series shortened to PC-98 or 98, is a lineup of Japanese 16-bit and 32-bit personal computers manufactured by NEC from 1982 through 2000. The platform established NEC's dominance in the Japanese personal computer market, by 1999, more than 18 million PC-98 units had been sold. NEC's Electronic Device Sales division launched the PC-8001 in 1979, it dominated 40% of the Japanese personal computer market in 1981; the vice president of NEC, Atsuyoshi Ōuchi thought "It is sure that we cannot deny contributions of Electronic Devices group as a parent of the personal computer. However, if personal computers are considered computers, Information Processing group should handle them in NEC. If personal computers are considered home electronics, we cannot deny a proposal from New Nippon Electric.". In April 1981, NEC decided to expand personal computer lines into three groups, New Nippon Electric did 8-bit home computers, Information Processing group did 16-bit business personal computers, Electronic Devices group did other personal computers.
In the Information Processing Small Systems division, Shunzō Hamada directed the project, Noboru Ozawa did the product planning. The development team planned the new personal computer as a small version of the business computer line which originated from the NEAC System 100 of 1973. Kazuya Watanabe, who directed the development of PC-8001, criticized that the personal computer must have Microsoft BASIC, provided peripheral devices compatible with previous NEC PCs, disclosed specifications of its expansion slot. In September 1981, Hamada requested Ascii's Kazuhiko Nishi to rewrite the N88-BASIC for the Intel 8086 processor. Nishi responded. Three months Nishi rejected his request because Microsoft was busy for developing GW-BASIC. Hamada wavered between two choices. While they were visiting software companies to collect and research applications for PC-8001 and PC-8801, they discovered that the consumer market wanted a 16-bit machine compatible with both PCs. Hamada decided to adopt two plans for different markets.
In April 1982, the small business personal computer became the NEC System 20 model 15 which used a proprietary 16-bit microprocessor. The machine was introduced as a new model of traditional business computers, so it wasn't notable. In February 1982, the software development team started the reverse engineering of N88-BASIC and the design of N88-BASIC. After the schedule estimation finished in the end of March 1982, the development of PC-9801, named N-10 Project, had started; the prototype of PC-9801 was completed in the end of July 1982. The code of N88-BASIC was written from scratch, but Nishi pointed the bytecode matched Microsoft's, it was unclear. Nishi proposed to Hamada that NEC must have purchased the same amount of Microsoft's product corresponded to the license fee, N88-BASIC must show copyright notification of both Microsoft and NEC. Hamada approved it; the team considered third-part developers were important for spreading the market. They provided technical information for independent companies without a fee.
In the Information Processing group, the Terminal Units division launched a personal computer series N5200 in 1981, branded as the personal terminal. It used a µPD7220 display controller, its architecture was similar to PC-98, but it ran a proprietary operating system named PTOS. The series was considered as an intelligent terminal or a workstation, it was distinguished with personal computer lines. For this market, Fujitsu released the FACOM 9450 in 1981, IBM Japan released the Multistation 5550 in 1983; the first model, the PC-9801, was launched in October 1982, employed an 8086 CPU. It ran at a clock speed of 5 MHz, with two µPD7220 display controllers, shipped with 128 KB of RAM, expandable to 640 KB, its 8-color display had a maximum resolution of 640×400 pixels. When the PC-9801 was launched in 1982, it was priced at 298,000 yen; this model required an expensive 8-inch floppy disk drive or smaller capacity of 320 KB 5¼-inch floppy drive. The basic system only had the ability to display JIS X 0201 characters including numbers, English alphabets, half-width kana, so most users added an optional Kanji ROM board for using Japanese word processor.
Its successor, the PC-9801F employed an 8086-2 CPU, which could selectively run at a speed of either 5 or 8 MHz. The F2 model contained two 640 KB 5¼-inch 2DD floppy drives, JIS level 1 kanji font ROM, was priced at 398,000 yen, it received a positive reception from businesses. Fujitsu released the FM-16β in December 1984, it had an a 1.2 MB 5 1/4 - inch 2HD floppy drive. The FM-16β failed because it bundled the CP/M-86, not MS-DOS, was marketed by Fujitsu's Electronic Devices department instead of the Computers department, they modified their policies in mid-1985. In another opinion, Fujitsu bundled a business software package with the FM-11, it discouraged users from purchasing third-part softwares, forced a specific purpose of use; as a result, Fujitsu failed to expand their platform. Against the release of FM-16β, NEC introduced the PC-9801M2; this model couldn't read a 2DD floppy disk
Wizardry is a series of role-playing video games, developed by Sir-Tech, which were influential in the evolution of modern role-playing video games. The original Wizardry was a significant influence on early console role-playing games such as Final Fantasy and Dragon Quest. Made for the Apple II, the games were ported to other platforms; the last game in the original series by Sir-Tech was Wizardry 8, released in 2001. There have since been various spin-off titles released only in Japan. Wizardry began as a simple dungeon crawl by Andrew C. Robert Woodhead, it was published by Sir-Tech. The game was influenced by earlier games from the PLATO system, most notably Oubliette; the earliest installments of Wizardry were successful, as they were the first graphically-rich incarnations of Dungeons & Dragons-type gameplay for home computers. The release of the first version coincided with the height of Dungeons & Dragons' popularity in North America; the first five games in the series were written in an implementation of UCSD Pascal.
They were ported to many different platforms by writing UCSD Pascal implementations for the target machines. David W. Bradley took over the series after the fourth installment, adding a new level of plot and complexity. In 1998, the rights were transferred to 1259190 Ontario Inc. and in 2006 to Aeria IPM. In 2008, Aeria IPM merged with the developer of Wizardry Online; the original Wizardry series is composed of eight different titles. All of the titles were first released in North America, ported to Japanese computers; some of the titles were officially released in Europe. The first three games are a trilogy, with similar settings and gameplay mechanics. A second trilogy is formed by installments 6 through 8 – Bane of the Cosmic Forge, Crusaders of the Dark Savant and Wizardry 8 – with settings and gameplay mechanics that differed from the first trilogy; the fourth game, The Return of Werdna, was a significant departure from the rest of the series. In it, the player controls Werdna, the evil wizard slain in the first game, summons groups of monsters to aid him as he fights his way through the prison in which he had been held captive.
Rather than monsters, the player faced typical adventuring parties, some of which were pulled from actual user disks sent to Sir-Tech for recovery. Further, the player had only a limited number of keystrokes to use to complete the game. In Japan, the Wizardry series was translated by ASCII Entertainment, became influential during the 1980s as its popularity at home declined; when first introduced, the games suffered from the culture barrier compounded by low-quality translation. This meant that the game was taken by players who overlooked the in-game jokes and parodies. For example, Blade Cusinart was introduced in early games as "a legendary sword made by the famous blacksmith, Cusinart " but its meaning was misinterpreted because Cuisinart food processors were unknown in Japan. However, this misconception appealed to early computer gamers who were looking for something different and made the Wizardry series popular. Conversely, the fourth game, The Return of Werdna, was poorly received, as, lacking the knowledge of subcultures necessary to solving the game, Japanese players had no chance of figuring out some puzzles.
The eight main titles in the series are: In 1996, the series received the first spin-off developed in North America, titled Wizardry Nemesis. It is played as a solo adventure: one character only, with monsters. All players attributes. In addition, the game contains only 16 spells, compared to 50 in the first four adventures, more in the subsequent ones, it is the first Wizardry title where the player saw enemies in advance and thus could try to avoid them. The popularity of Wizardry in Japan inspired several original sequels and ports, with the series long outliving the American original; as of 2017, thirty-nine different spin-offs were released in Japan, with four of them making their way to North America: Wizardry: Tale of the Forsaken Land, Wizardry: Labyrinth of Lost Souls, Wizardry Online and Wizrogue: Labyrinth of Wizardry. The latest is the last original game produced in the series, released in Japan in 2014, released in English worldwide in 2017; the original Wizardry game was a success, selling 24,000 copies by June 1982, just nine months after its release according to Softalk‘s sales surveys.
In the June 1983 issue of Electronic Games, Wizardry was described as "without a doubt, the most popular fantasy adventure game for the Apple II at the present time". While noting limitations such as the inability to divide the party, or the emphasis on combat over role-playing, the magazine stated that "no other game comes closer to providing the type of contest favored by most players of non-electronic role-playing games... one outstanding programming achievement, an absolute'must buy' for those fantasy gamers who own an Apple". Spin-offs released in Japan received positive reviews in North America. Gamespot reviewed Wizardry: Tale of the Forsaken Land in 2002 and awarded it a score of 8.5 out of 10. In 2011, Wizardry: Labyrinth of Lost Souls was reviewed by Gamespot and received a score of 7.5 out of 10. In Japan, readers of Famitsu magazine considered the Famicom port of the original Wizardry I to be one of the 100 best games of all time; the series was ranked as the 60th top game by Next Generation in 1996.

Super Nintendo Entertainment System
The Super Nintendo Entertainment System known as the Super NES or Super Nintendo, is a 16-bit home video game console developed by Nintendo, released in 1990 in Japan and South Korea, 1991 in North America, 1992 in Europe and Australasia, 1993 in South America. In Japan, the system is called the Super Famicom. In South Korea, it was distributed by Hyundai Electronics; the system was released in Brazil on August 1993, by Playtronic. Although each version is the same, several forms of regional lockout prevent the different versions from being compatible with one another; the SNES is Nintendo's second programmable home console, following the Nintendo Entertainment System. The console introduced advanced graphics and sound capabilities compared with other systems at the time; the development of a variety of enhancement chips integrated in game cartridges helped to keep it competitive in the marketplace. The SNES was a global success, becoming the best-selling console of the 16-bit era despite its late start and the intense competition it faced in North America and Europe from Sega's Genesis console.
The SNES remained popular well into the 32-bit era having sold 49.1 million worldwide by the time it was discontinued in 2003.. It continues to be popular among collectors and retro gamers, some of whom still make homebrew ROM images, in addition to its popularity in Nintendo's emulated rereleases, such as on the Virtual Console and the Super NES Classic Edition. To compete with the popular Family Computer in Japan, NEC Home Electronics launched the PC Engine in 1987, Sega followed suit with the Mega Drive in 1988; the two platforms were launched in North America in 1989 as the TurboGrafx-16 and the Sega Genesis, respectively. Both systems were built on 16-bit architectures and offered improved graphics and sound over the 8-bit NES. However, it took several years for Sega's system to become successful. Nintendo executives were in no rush to design a new system, but they reconsidered when they began to see their dominance in the market slipping. Designed by Masayuki Uemura, the designer of the original Famicom, the Super Famicom was released in Japan on Wednesday, November 21, 1990 for 25,000 yen.
It was an instant success. The system's release gained the attention of the Yakuza, leading to a decision to ship the devices at night to avoid robbery. With the Super Famicom outselling its rivals, Nintendo reasserted itself as the leader of the Japanese console market. Nintendo's success was due to the retention of most of its key third-party developers, including Capcom, Tecmo, Square and Enix. Nintendo released the Super Nintendo Entertainment System, a redesigned version of the Super Famicom, in North America for $199, it began shipping in limited quantities on August 23, 1991, with an official nationwide release date of September 9, 1991. The SNES was released in the United Kingdom and Ireland in April 1992 for £150, with a German release following a few weeks later. Most of the PAL region versions of the console use the Japanese Super Famicom design, except for labeling and the length of the joypad leads; the Playtronic Super NES in Brazil, although PAL-M, uses the North American design.
Both the NES and SNES were released in Brazil in 1993 by Playtronic, a joint venture between the toy company Estrela and consumer electronics company Gradiente. The SNES and Super Famicom launched with few games, but these games were well received in the marketplace. In Japan, only two games were available: Super Mario World and F-Zero. In North America, Super Mario World launched as a bundle with the console; the rivalry between Nintendo and Sega resulted in what has been described as one of the most notable console wars in video game history, in which Sega positioned the Genesis as the "cool" console, with games aimed at older audiences, advertisements that attacked the competition. Nintendo however, scored an early public relations advantage by securing the first console conversion of Capcom's arcade classic Street Fighter II for SNES, which took over a year to make the transition to the Genesis. Despite the Genesis's head start, much larger library of games, lower price point, the Genesis only represented an estimated 60% of the American 16-bit console market in June 1992, neither console could maintain a definitive lead for several years.
Donkey Kong Country is said to have helped establish the SNES's market prominence in the latter years of the 16-bit generation, for a time, maintain against the PlayStation and Saturn. According to Nintendo, the company had sold more than 20 million SNES units in the U. S. According to a 2014 Wedbush Securities report based on NPD sales data, the SNES outsold the Genesis in the U. S. market. During the NES era, Nintendo maintained exclusive control over games released for the system—the company had to approve every game, each third-party developer could only release up to five games per year, those games could not be released on another console within two years, Nintendo was the exclusive manufacturer and supplier of NES cartridges
In Greek mythology, the Amazons were a tribe of women warriors related to Scythians and Sarmatians. Apollonius Rhodius, at Argonautica, mentions that Amazons were the daughters of Harmonia, they were brutal and aggressive, their main concern in life was war. Lysias, Philostratus the Elder say that their father was Ares. Herodotus and Strabo place them on the banks of the Thermodon River. According to Diodorus, giving the account of Dionysius of Mitylene, the Amazons inhabited Ancient Libya long before they settled along the Thermodon. Migrating from Libya, these Amazons passed through Egypt and Syria, stopped at the Caïcus in Aeolis, near which they founded several cities. Diodorus maintains, they established Mytilene a little way beyond the Caïcus. Aeschylus, in Prometheus Bound, places the original home of the Amazons in the country about Lake Maeotis, from which they moved to Themiscyra on the Thermodon. Homer tells that the Amazons were found somewhere near Lycia. Notable queens of the Amazons are Penthesilea, who participated in the Trojan War, her sister Hippolyta, whose magical girdle, given to her by her father Ares, was the object of one of the labours of Heracles.
Diodorus mentions. Amazon warriors were depicted in battle with Greek warriors in amazonomachies in classical art. Archaeological discoveries of burial sites with female warriors on the Eurasian steppes suggest that the Scythian women may have inspired the Amazon myth. From the early modern period, their name has become a term for female warriors in general. Amazons were said to have founded the cities and temples of Smyrna, Cyme, Ephesus, Magnesia, Pygela and Amastris. Palaephatus, trying to rationalize the Greek myths in his On Unbelievable Tales, wrote that the Amazons were men, but their enemies mistook for women by because they wore clothing which reached their feet, tied up their hair in headbands and shaved their beards, in addition, because they did not exist during his time, most they did nοt exist in the past either; the origin of the word is uncertain. It may be derived from an Iranian ethnonym *ha-mazan- "warriors", a word attested indirectly through a derivation, a denominal verb in Hesychius of Alexandria's gloss "ἁμαζακάραν· πολεμεῖν.
Πέρσαι", where it appears together with the Indo-Iranian root *kar- "make". It may be derived from *ṇ-mṇ-gw-jon-es "manless, without husbands" has been proposed, an explanation deemed "unlikely" by Hjalmar Frisk. 19th-century scholarship connected the term to the ethnonym Amazigh. A further explanation proposes Iranian *ama-janah "virility-killing" as source; the Hittite researcher Friedrich Cornelius assumes that there had been the land Azzi with the capital Chajasa in the area of the Thermodon-Iris Delta on the coast of the Black Sea. He brings its residents in direct relation to the Amazons, namely based on its customs; the location of that land as well as his conclusions are controversial. Among Classical Greeks, amazon was given a folk etymology as originating from a- and mazos, "without breast", connected with an etiological tradition once claimed by Marcus Justinus who alleged that Amazons had their right breast cut off or burnt out. There is no indication of such a practice in ancient works of art, in which the Amazons are always represented with both breasts, although one is covered.
Adrienne Mayor suggests. Greeks used some descriptive phrases for them. Herodotus used the Androktones and Androleteirai, in the Iliad they are called Antianeirai and Aeschylus, in his work Prometheus Bound, used styganor. Herodotus and Strabo placed them on the banks of the Themiscyra. Herodotus mentions that some Amazons lived at Scythia because after the Greeks defeated the Amazons in battle, they sailed away carrying in three ships as many Amazons as they had been able to take alive, but out at sea the Amazons attacked the crews and killed them these Amazons landed at Scythian lands. Strabo writes that the original home of the Amazons was in Themiscyra and the plains about Thermodon and the mountains that lie above them, but were driven out of these places, during his time they were said to live in the mountains above Caucasian Albania, but he states that some others, among them Metrodorus of Scepsis and Hypsicrates, say that after Themiscyra, the Amazons traveled and lived on the borders of the Gargarians, in the northerly foothills of those parts of the Caucasian Mountains which are called Ceraunian.
Diodorus giving the account of Dionysius of Mitylene, who, on his part, drew on Thymoetas states that before the Amazons of the Thermodon there were, much earlier in time, the Amazons of Libya. These Amazons started from Libya passed through Egypt and Syria, stopped at the Caïcus in Aeolis, near which they founded several cities, he says, they es
Star Wars is an American epic space-opera media franchise created by George Lucas. The franchise began with the eponymous 1977 film and became a worldwide pop-culture phenomenon; the first film subtitled Episode IV – A New Hope, was followed by two successful sequels, Episode V – The Empire Strikes Back and Episode VI – Return of the Jedi. A subsequent prequel trilogy, consisting of Episode I – The Phantom Menace, Episode II – Attack of the Clones and Episode III – Revenge of the Sith, completed what Lucas called the "tragedy of Darth Vader". A sequel trilogy began with Episode VII – The Force Awakens, continued with Episode VIII – The Last Jedi, will end with Episode IX – The Rise of Skywalker in 2019; the first eight films were commercially successful. Together with the theatrical spin-off films Rogue One and Solo, the series has a combined box office revenue of over US$9 billion, is the second-highest-grossing film franchise; the film series has spawned into other media, including television series, video games, comics, theme park attractions and themed areas, resulting in a detailed fictional universe.
Star Wars holds a Guinness World Records title for the "Most successful film merchandising franchise". In 2018, the total value of the Star Wars franchise was estimated at US$65 billion, it is the fifth-highest-grossing media franchise of all time; the Star Wars franchise depicts the adventures of characters "A long time ago in a galaxy far, far away...." in which many species of aliens co-exist with droids who may assist them in their daily routines, space travel between planets is common due to hyperspace technology. The rises and falls of different governments are chronicled throughout the saga: the democratic Republic is corrupted and overthrown by the Galactic Empire, fought by the Rebel Alliance; the Rebellion gives rise to the New Republic and rebuilds society, but the remnants of the Empire reform as the First Order and attempt to destroy the Republic. Heroes of the former rebellion lead the Resistance against the oppressive dictatorship. A mystical power known as "the Force" is described in the original film as "an energy field created by all living things... binds the galaxy together."
Those whom "the Force is strong with" have quick reflexes. The Force is wielded by two major knighthood orders at conflict with each other: the Jedi, who act on the light side of the Force through non-attachment and arbitration, the Sith, who use the dark side through fear and aggression; the latter's members are intended to be limited to two: their apprentice. The Star Wars film series centers on a trilogy of trilogies, they were produced non-chronologically, with Episodes IV–VI being released between 1977 and 1983, Episodes I–III being released between 1999 and 2005, Episodes VII–IX, the first Star Wars films to be made without Lucas's direct involvement, being released between 2015 and 2019. Each trilogy focuses on a generation of the Force-sensitive Skywalker family; the original trilogy depict the heroic development of Luke Skywalker, the prequels tell of his father Anakin's fall from grace, the sequels introduce Luke's nephew and Anakin's grandson, Kylo Ren. A theatrical animated film, The Clone Wars, was released as a pilot to a TV series of the same name.
They were among the last projects overseen by George Lucas before the franchise was sold to Disney in 2012. An anthology series set between the main episodes entered development in parallel to the production of the sequel trilogy, described by Disney CFO Jay Rasulo as origin stories; the first entry, Rogue One, tells the story of the rebels who steal the Death Star plans directly before Episode IV. Solo: A Star Wars Story focuses on Han Solo's backstory featuring Chewbacca and Lando Calrissian. Two spin-off trilogies have been announced: one by Episode VIII's director Rian Johnson and the other by Game of Thrones creators David Benioff and D. B. Weiss. Prequel trilogy Original trilogy Sequel trilogy In 1971, George Lucas wanted to film an adaptation of the Flash Gordon serial, but couldn't obtain the rights, so he began developing his own space opera. After directing American Graffiti, he wrote a two-page synopsis titled Journal of the Whills, which 20th Century Fox decided to invest in. By 1974, he had expanded the story into the first draft of a screenplay.
The subsequent movie's success led Lucas to make it the basis of an elaborate film serial. With the backstory he created for the sequel, Lucas decided that the series would be a trilogy of trilogies. Most of the main cast would return for the two additional installments of the original trilogy, which were self-financed by Lucasfilm. Star Wars was released on May 25, 1977 and first called Episode IV – A New Hope in the 1979 book The Art of Star Wars. Episode V – The Empire Strikes Back was released on May 21, 1980 achieving wide financial and critical success; the final film in the trilogy, Episode VI – Return of the Jedi was released on May 25, 1983. The story of the original trilogy focuses on Luke Skywalker's quest to become a Jedi, his struggle with the evil Imperial agent Darth Vader, the struggle of the Rebel Alliance to free the galaxy from the clutches of the Empire. According to producer Gary Kurtz, lo
The Macintosh is a family of personal computers designed and sold by Apple Inc. since January 1984. The original Macintosh was the first mass-market personal computer that featured a graphical user interface, built-in screen and mouse. Apple sold the Macintosh alongside its popular Apple II family of computers for ten years before they were discontinued in 1993. Early Macintosh models were expensive, hindering its competitiveness in a market dominated by the Commodore 64 for consumers, as well as the IBM Personal Computer and its accompanying clone market for businesses. Macintosh systems still found success in education and desktop publishing and kept Apple as the second-largest PC manufacturer for the next decade. In the early 1990s, Apple introduced models such as the Macintosh LC II and Color Classic which were price-competitive with Wintel machines at the time. However, the introduction of Windows 3.1 and Intel's Pentium processor which beat the Motorola 68040 in most benchmarks took market share from Apple, by the end of 1994 Apple was relegated to third place as Compaq became the top PC manufacturer.
After the transition to the superior PowerPC-based Power Macintosh line in the mid-1990s, the falling prices of commodity PC components, poor inventory management with the Macintosh Performa, the release of Windows 95 saw the Macintosh user base decline. Prompted by the returning Steve Jobs' belief that the Macintosh line had become too complex, Apple consolidated nearly twenty models in mid-1997 down to four in mid-1999: The Power Macintosh G3, iMac, 14.1" PowerBook G3, 12" iBook. All four products were critically and commercially successful due to their high performance, competitive prices and aesthetic designs, helped return Apple to profitability. Around this time, Apple phased out the Macintosh name in favor of "Mac", a nickname, in common use since the development of the first model. Since their transition to Intel processors in 2006, the complete lineup is based on said processors and associated systems, its current lineup includes four desktops, three laptops. Its Xserve server was discontinued in 2011 in favor of the Mac Mac Pro.
Apple has developed a series of Macintosh operating systems. The first versions had no name but came to be known as the "Macintosh System Software" in 1988, "Mac OS" in 1997 with the release of Mac OS 7.6, retrospectively called "Classic Mac OS". In 2001, Apple released Mac OS X, a modern Unix-based operating system, rebranded to OS X in 2012, macOS in 2016; the current version is macOS Mojave, released on September 24, 2018. Intel-based Macs are capable of running non-Apple operating systems such as Linux, OpenBSD, Microsoft Windows with the aid of Boot Camp or third-party software. Apple produced a Unix-based operating system for the Macintosh called A/UX from 1988 to 1995, which resembled contemporary versions of the Macintosh system software. Apple does not license macOS for use on non-Apple computers, however System 7 was licensed to various companies through Apple's Macintosh clone program from 1995 to 1997. Only one company, UMAX Technologies was licensed to ship clones running Mac OS 8.
Since Apple's transition to Intel processors, there is a sizeable community around the world that specialises in hacking macOS to run on non-Apple computers, which are called "Hackintoshes". The Macintosh project began in 1979 when Jef Raskin, an Apple employee, envisioned an easy-to-use, low-cost computer for the average consumer, he wanted to name the computer after his favorite type of apple, the McIntosh, but the spelling was changed to "Macintosh" for legal reasons as the original was the same spelling as that used by McIntosh Laboratory, Inc. the audio equipment manufacturer. Steve Jobs requested that McIntosh Laboratory give Apple a release for the newly spelled name, thus allowing Apple to use it; the request was denied, forcing Apple to buy the rights to use this name. In 1978, Apple began to organize the Apple Lisa project, aiming to build a next-generation machine similar to an advanced Apple II or the yet-to-be-introduced IBM PC. In 1979, Steve Jobs learned of the advanced work on graphical user interfaces taking place at Xerox PARC.
He arranged for Apple engineers to be allowed to visit PARC to see the systems in action. The Apple Lisa project was redirected to utilize a GUI, which at that time was well beyond the state of the art for microprocessor capabilities. Things had changed with the introduction of the 32-bit Motorola 68000 in 1979, which offered at least an order of magnitude better performance than existing designs, made a software GUI machine a practical possibility; the basic layout of the Lisa was complete by 1982, at which point Jobs's continual suggestions for improvements led to him being kicked off the project. At the same time that the Lisa was becoming a GUI machine in 1979, Jef Raskin started the Macintosh project; the design at that time was for a easy-to-use machine for the average consumer. In
