Germany the Federal Republic of Germany, is a country in Central and Western Europe, lying between the Baltic and North Seas to the north, the Alps to the south. It borders Denmark to the north and the Czech Republic to the east and Switzerland to the south, France to the southwest, Luxembourg and the Netherlands to the west. Germany includes 16 constituent states, covers an area of 357,386 square kilometres, has a temperate seasonal climate. With 83 million inhabitants, it is the second most populous state of Europe after Russia, the most populous state lying in Europe, as well as the most populous member state of the European Union. Germany is a decentralized country, its capital and largest metropolis is Berlin, while Frankfurt serves as its financial capital and has the country's busiest airport. Germany's largest urban area is the Ruhr, with its main centres of Essen; the country's other major cities are Hamburg, Cologne, Stuttgart, Düsseldorf, Dresden, Bremen and Nuremberg. 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. After the collapse of the Holy Roman Empire, the German Confederation was formed in 1815; the German revolutions of 1848–49 resulted in the Frankfurt Parliament establishing major democratic rights. 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 revolution of 1918–19, the Empire was replaced by the parliamentary Weimar Republic; the Nazi seizure of power in 1933 led to the establishment of a dictatorship, the annexation of Austria, World War II, the Holocaust. After the end of World War II in Europe and a period of Allied occupation, Austria was re-established as an independent country and two new German states were founded: West Germany, formed from the American and French occupation zones, East Germany, formed from the Soviet occupation zone.
Following the Revolutions of 1989 that ended communist rule in Central and Eastern Europe, the country was reunified on 3 October 1990. Today, the sovereign state of Germany is a federal parliamentary republic led by a chancellor, it is a great power with a strong economy. As a global leader in several industrial and technological sectors, it is both the world's third-largest exporter and importer of goods; as a developed country with a high standard of living, it upholds a social security and universal health care system, environmental protection, a tuition-free university education. The Federal Republic of Germany was a founding member of the European Economic Community in 1957 and the European Union in 1993, 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 G7, the G20, the OECD. Known for its rich cultural history, Germany has been continuously the home of influential and successful artists, musicians, film people, entrepreneurs, scientists and inventors.
Germany has a large number of World Heritage sites and is among the top tourism destinations 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; the German term Deutschland diutisciu land is derived from deutsch, descended from Old High German diutisc "popular" used to distinguish the language of the common people from Latin and its Romance descendants. This in turn descends from Proto-Germanic *þiudiskaz "popular", derived from *þeudō, descended from Proto-Indo-European *tewtéh₂- "people", from which the word Teutons originates; 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 coal mine in Schöningen between 1994 and 1998 where eight 380,000-year-old wooden javelins of 1.82 to 2.25 m length were unearthed. The Neander Valley was the location where the first non-modern human fossil was discovered.
The Neanderthal 1 fossils are known to be 40,000 years old. Evidence of modern humans dated, has been found in caves in the Swabian Jura near Ulm; the finds included 42,000-year-old bird bone and mammoth ivory flutes which are the oldest musical instruments found, the 40,000-year-old Ice Age Lion Man, the oldest uncontested figurative art discovered, the 35,000-year-old Venus of Hohle Fels, the oldest uncontested human figurative art discovered. The Nebra sky disk is a bronze artefact created during the European Bronze Age attributed to a site near Nebra, Saxony-Anhalt, it is part of UNESCO's Memory of the World Programme. The Germanic tribes are thought to date from the Pre-Roman Iron Age. From southern Scandinavia and north Germany, they expanded south and west from the 1st century BC, coming into contact with the Celtic tribes of Gaul as well
A floppy disk known as a floppy, diskette, or disk, is a type of disk storage composed of a disk of thin and flexible magnetic storage medium, sealed in a rectangular plastic enclosure lined with fabric that removes dust particles. Floppy disks are written by a floppy disk drive. Floppy disks as 8-inch media and in 5 1⁄4-inch and 3 1⁄2 inch sizes, were a ubiquitous form of data storage and exchange from the mid-1970s into the first years of the 21st century. By 2006 computers were manufactured with installed floppy disk drives; these formats are handled by older equipment. The prevalence of floppy disks in late-twentieth century culture was such that many electronic and software programs still use the floppy disks as save icons. While floppy disk drives still have some limited uses with legacy industrial computer equipment, they have been superseded by data storage methods with much greater capacity, such as USB flash drives, flash storage cards, portable external hard disk drives, optical discs, cloud storage and storage available through computer networks.
The first commercial floppy disks, developed in the late 1960s, were 8 inches in diameter. These disks and associated drives were produced and improved upon by IBM and other companies such as Memorex, Shugart Associates, Burroughs Corporation; the term "floppy disk" appeared in print as early as 1970, although IBM announced its first media as the "Type 1 Diskette" in 1973, the industry continued to use the terms "floppy disk" or "floppy". In 1976, Shugart Associates introduced the 5 1⁄4-inch FDD. By 1978 there were more than 10 manufacturers producing such FDDs. There were competing floppy disk formats, with hard- and soft-sector versions and encoding schemes such as FM, MFM, M2FM and GCR; the 5 1⁄4-inch format displaced the 8-inch one for most applications, the hard-sectored disk format disappeared. The most common capacity of the 5 1⁄4-inch format in DOS-based PCs was 360 KB, for the DSDD format using MFM encoding. In 1984 IBM introduced with its PC-AT model the 1.2 MB dual-sided 5 1⁄4-inch floppy disk, but it never became popular.
IBM started using the 720 KB double-density 3 1⁄2-inch microfloppy disk on its Convertible laptop computer in 1986 and the 1.44 MB high-density version with the PS/2 line in 1987. These disk drives could be added to older PC models. In 1988 IBM introduced a drive for 2.88 MB "DSED" diskettes in its top-of-the-line PS/2 models, but this was a commercial failure. Throughout the early 1980s, limitations of the 5 1⁄4-inch format became clear. Designed to be more practical than the 8-inch format, it was itself too large. A number of solutions were developed, with drives at 2-, 2 1⁄2-, 3-, 3 1⁄4-, 3 1⁄2- and 4-inches offered by various companies, they all shared a number of advantages over the old format, including a rigid case with a sliding metal shutter over the head slot, which helped protect the delicate magnetic medium from dust and damage, a sliding write protection tab, far more convenient than the adhesive tabs used with earlier disks. The large market share of the well-established 5 1⁄4-inch format made it difficult for these diverse mutually-incompatible new formats to gain significant market share.
A variant on the Sony design, introduced in 1982 by a large number of manufacturers, was rapidly adopted. The term floppy disk persisted though style floppy disks have a rigid case around an internal floppy disk. By the end of the 1980s, 5 1⁄4-inch disks had been superseded by 3 1⁄2-inch disks. During this time, PCs came equipped with drives of both sizes. By the mid-1990s, 5 1⁄4-inch drives had disappeared, as the 3 1⁄2-inch disk became the predominant floppy disk; the advantages of the 3 1⁄2-inch disk were its higher capacity, its smaller size, its rigid case which provided better protection from dirt and other environmental risks. If a person touches the exposed disk surface of a 5 1⁄4-inch disk through the drive hole, fingerprints may foul the disk—and the disk drive head if the disk is subsequently loaded into a drive—and it is easily possible to damage a disk of this type by folding or creasing it rendering it at least unreadable; however due to its simpler construction the 5 1⁄4-inch disk unit price was lower throughout its history in the range of a third to a half that of a 3 1⁄2-inch disk.
Floppy disks became commonplace during the 1980s and 1990s in their use with personal computers to distribute software, transfer data, create backups. Before hard disks became affordable to the general population, floppy disks were used to store a computer's operating system. Most home computers from that period have an elementary OS and BASIC stored in ROM, with the option of loading a more advanced operating system from a floppy disk. By the early 1990s, the increasing software size meant large packages like Windows or Adobe Photoshop required a dozen disks or more. In 1996, there were an estimated five billion standard floppy disks in use. Distribution of larger packages was replaced by CD-ROMs, DVDs and online distribution. An
An operating system is system software that manages computer hardware and software resources and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may include accounting software for cost allocation of processor time, mass storage and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is executed directly by the hardware and makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer – from cellular phones and video game consoles to web servers and supercomputers; the dominant desktop operating system is Microsoft Windows with a market share of around 82.74%. MacOS by Apple Inc. is in second place, the varieties of Linux are collectively in third place. In the mobile sector, use in 2017 is up to 70% of Google's Android and according to third quarter 2016 data, Android on smartphones is dominant with 87.5 percent and a growth rate 10.3 percent per year, followed by Apple's iOS with 12.1 percent and a per year decrease in market share of 5.2 percent, while other operating systems amount to just 0.3 percent.
Linux distributions are dominant in supercomputing sectors. Other specialized classes of operating systems, such as embedded and real-time systems, exist for many applications. A single-tasking system can only run one program at a time, while a multi-tasking operating system allows more than one program to be running in concurrency; this is achieved by time-sharing, where the available processor time is divided between multiple processes. These processes are each interrupted in time slices by a task-scheduling subsystem of the operating system. Multi-tasking may be characterized in co-operative types. In preemptive multitasking, the operating system slices the CPU time and dedicates a slot to each of the programs. Unix-like operating systems, such as Solaris and Linux—as well as non-Unix-like, such as AmigaOS—support preemptive multitasking. Cooperative multitasking is achieved by relying on each process to provide time to the other processes in a defined manner. 16-bit versions of Microsoft Windows used cooperative multi-tasking.
32-bit versions of both Windows NT and Win9x, used preemptive multi-tasking. Single-user operating systems have no facilities to distinguish users, but may allow multiple programs to run in tandem. A multi-user operating system extends the basic concept of multi-tasking with facilities that identify processes and resources, such as disk space, belonging to multiple users, the system permits multiple users to interact with the system at the same time. Time-sharing operating systems schedule tasks for efficient use of the system and may include accounting software for cost allocation of processor time, mass storage and other resources to multiple users. A distributed operating system manages a group of distinct computers and makes them appear to be a single computer; the development of networked computers that could be linked and communicate with each other gave rise to distributed computing. Distributed computations are carried out on more than one machine; when computers in a group work in cooperation, they form a distributed system.
In an OS, distributed and cloud computing context, templating refers to creating a single virtual machine image as a guest operating system saving it as a tool for multiple running virtual machines. The technique is used both in virtualization and cloud computing management, is common in large server warehouses. Embedded operating systems are designed to be used in embedded computer systems, they are designed to operate on small machines like PDAs with less autonomy. They are able to operate with a limited number of resources, they are compact and efficient by design. Windows CE and Minix 3 are some examples of embedded operating systems. A real-time operating system is an operating system that guarantees to process events or data by a specific moment in time. A real-time operating system may be single- or multi-tasking, but when multitasking, it uses specialized scheduling algorithms so that a deterministic nature of behavior is achieved. An event-driven system switches between tasks based on their priorities or external events while time-sharing operating systems switch tasks based on clock interrupts.
A library operating system is one in which the services that a typical operating system provides, such as networking, are provided in the form of libraries and composed with the application and configuration code to construct a unikernel: a specialized, single address space, machine image that can be deployed to cloud or embedded environments. Early computers were built to perform a series of single tasks, like a calculator. Basic operating system features were developed in the 1950s, such as resident monitor functions that could automatically run different programs in succession to speed up processing. Operating systems did not exist in their more complex forms until the early 1960s. Hardware features were added, that enabled use of runtime libraries and parallel processing; when personal computers became popular in the 1980s, operating systems were made for them similar in concept to those used on larger computers. In the 1940s, the earliest electronic digital systems had no operating systems.
Electronic systems of this time were programmed on rows of mechanical switches or by jumper wires on plug boards. These were special-purpose systems that, for example, generated ballistics tables for the military or controlled the pri
MS-DOS is an operating system for x86-based personal computers developed by Microsoft. Collectively, MS-DOS, its rebranding as IBM PC DOS, some operating systems attempting to be compatible with MS-DOS, are sometimes referred to as "DOS". MS-DOS was the main operating system for IBM PC compatible personal computers during the 1980s and the early 1990s, when it was superseded by operating systems offering a graphical user interface, in various generations of the graphical Microsoft Windows operating system. MS-DOS was the result of the language developed in the seventies, used by IBM for its mainframe operating system. Microsoft acquired the rights to meet IBM specifications. IBM re-released it on August 12, 1981 as PC DOS 1.0 for use in their PCs. Although MS-DOS and PC DOS were developed in parallel by Microsoft and IBM, the two products diverged after twelve years, in 1993, with recognizable differences in compatibility and capabilities. During its lifetime, several competing products were released for the x86 platform, MS-DOS went through eight versions, until development ceased in 2000.
MS-DOS was targeted at Intel 8086 processors running on computer hardware using floppy disks to store and access not only the operating system, but application software and user data as well. Progressive version releases delivered support for other mass storage media in greater sizes and formats, along with added feature support for newer processors and evolving computer architectures, it was the key product in Microsoft's growth from a programming language company to a diverse software development firm, providing the company with essential revenue and marketing resources. It was the underlying basic operating system on which early versions of Windows ran as a GUI, it is a flexible operating system, consumes negligible installation space. MS-DOS was a renamed form of 86-DOS – owned by Seattle Computer Products, written by Tim Paterson. Development of 86-DOS took only six weeks, as it was a clone of Digital Research's CP/M, ported to run on 8086 processors and with two notable differences compared to CP/M.
This first version was shipped in August 1980. Microsoft, which needed an operating system for the IBM Personal Computer hired Tim Paterson in May 1981 and bought 86-DOS 1.10 for $75,000 in July of the same year. Microsoft kept the version number, but renamed it MS-DOS, they licensed MS-DOS 1.10/1.14 to IBM, who, in August 1981, offered it as PC DOS 1.0 as one of three operating systems for the IBM 5150, or the IBM PC. Within a year Microsoft licensed MS-DOS to over 70 other companies, it was designed to be an OS. Each computer would have its own distinct hardware and its own version of MS-DOS, similar to the situation that existed for CP/M, with MS-DOS emulating the same solution as CP/M to adapt for different hardware platforms. To this end, MS-DOS was designed with a modular structure with internal device drivers, minimally for primary disk drives and the console, integrated with the kernel and loaded by the boot loader, installable device drivers for other devices loaded and integrated at boot time.
The OEM would use a development kit provided by Microsoft to build a version of MS-DOS with their basic I/O drivers and a standard Microsoft kernel, which they would supply on disk to end users along with the hardware. Thus, there were many different versions of "MS-DOS" for different hardware, there is a major distinction between an IBM-compatible machine and an MS-DOS machine; some machines, like the Tandy 2000, were MS-DOS compatible but not IBM-compatible, so they could run software written for MS-DOS without dependence on the peripheral hardware of the IBM PC architecture. This design would have worked well for compatibility, if application programs had only used MS-DOS services to perform device I/O, indeed the same design philosophy is embodied in Windows NT. However, in MS-DOS's early days, the greater speed attainable by programs through direct control of hardware was of particular importance for games, which pushed the limits of their contemporary hardware. Soon an IBM-compatible architecture became the goal, before long all 8086-family computers emulated IBM's hardware, only a single version of MS-DOS for a fixed hardware platform was needed for the market.
This version is the version of MS-DOS, discussed here, as the dozens of other OEM versions of "MS-DOS" were only relevant to the systems they were designed for, in any case were similar in function and capability to some standard version for the IBM PC—often the same-numbered version, but not always, since some OEMs used their own proprietary version numbering schemes —with a few notable exceptions. Microsoft omitted multi-user support from MS-DOS because Microsoft's Unix-based operating system, was multi-user; the company planned, over time, to improve MS-DOS so it would be indistinguishable from single-user Xenix, or XEDOS, which would run on the Motorola 68000, Zilog Z8000, the LSI-11. Microsoft advertised MS-DOS and Xenix together, listing the shared features of its "single-user OS" and "the multi-user, multi-tasking, UNIX-derived operating system", promising easy
Turbo C++ is a discontinued C++ compiler and integrated development environment and computer language from Borland. Most it was distributed by Embarcadero Technologies, which acquired all of Borland's compiler tools with the purchase of its CodeGear division in 2008; the original Turbo C++ product line was put on hold after 1994 and was revived in 2006 as an introductory-level IDE a stripped-down version of their flagship C++Builder. Turbo C++ 2006 was released on September 5, 2006 and was available in'Explorer' and'Professional' editions; the Explorer edition was free to download and distribute while the Professional edition was a commercial product. In October 2009 Embarcadero Technologies discontinued support of its 2006 C++ editions; as such, the Explorer edition is no longer available for download and the Professional edition is no longer available for purchase from Embarcadero Technologies. Turbo C++ is succeeded by C++Builder; the first release of Turbo C++ was made available during the MS-DOS era on personal computers.
Version 1.0, running on MS-DOS, was released in May 1990. An OS/2 version was produced as well. Version 1.01 was released on February 28, 1991, running on MS-DOS. The latter was able to generate both COM and EXE programs and was shipped with Borland's Turbo Assembler compiler for Intel x86 processors; the initial version of the Turbo C++ compiler was based on a front end developed by TauMetric. This compiler supported the AT&T 2.0 release of C++. Turbo C++ 3.0 was released in 1991, came in amidst expectations of the coming release of Turbo C++ for Microsoft Windows. Released as an MS-DOS compiler, 3.0 supported C++ templates, Borland's inline assembler, generation of MS-DOS mode executables for both 8086 real mode and 286 protected mode 3.0 implemented AT&T C++ 2.1, the most recent at the time. The separate Turbo Assembler product was no longer included, but the inline-assembler could stand in as a reduced functionality version. Soon after the release of Windows 3.0, Borland updated Turbo C++ to support Windows application development.
The Turbo C++ 3.0 for Windows product was followed by Turbo C++ 3.1. It's possible that the jump from version 1.x to version 3.x was in part an attempt to link Turbo C++ release numbers with Microsoft Windows versions. Starting with version 3.0, Borland segmented their C++ compiler into two distinct product-lines: "Turbo C++" and "Borland C++". Turbo C++ was marketed toward the hobbyist and entry-level compiler market, while Borland C++ targeted the professional application development market. Borland C++ included additional tools, compiler code-optimization, documentation to address the needs of commercial developers. Turbo C++ 3.0 could be upgraded with separate add-ons, such as Turbo Assembler and Turbo Vision 1.0. Version 4.0 was notable for its robust support of templates. In particular, Borland C++ 4 was instrumental in the development of the Standard Template Library, expression templates, the first advanced applications of template metaprogramming. With the success of the Pascal-evolved product Delphi, Borland ceased work on their Borland C++ suite and concentrated on C++Builder for Windows.
C++Builder shared Delphi's front-end application framework, but retained the Borland C++ back-end compiler. Active development on Borland C++/Turbo C++ was suspended until 2006 Turbo C++ v1.01 and Turbo C v2.01 can be downloaded, free of charge, from Borland's Antique Software website. Turbo C 3.0 was included in the Turbo C Suite 1.0, no longer sold by Borland.

The Atari ST is a line of home computers from Atari Corporation and the successor to the Atari 8-bit family. The initial ST model, the 520ST, saw limited release in April–June 1985 and was available in July; the Atari ST is the first personal computer to come with a bitmapped color GUI, using a version of Digital Research's GEM released in February 1985. The 1040ST, released in 1986, is the first personal computer to ship with a megabyte of RAM in the base configuration and the first with a cost-per-kilobyte of less than US$1; the Atari ST is part of a mid-1980s generation of home computers that have 16 or 32-bit processors, 256 KB or more of RAM, mouse-controlled graphical user interfaces. This generation includes the Macintosh, Commodore Amiga, Apple IIGS, and, in certain markets, the Acorn Archimedes. "ST" stands for "Sixteen/Thirty-two", which refers to the Motorola 68000's 16-bit external bus and 32-bit internals. The ST was sold with the less expensive monochrome monitor; the system's two color graphics modes are only available on the former while the highest-resolution mode needs the monochrome monitor.
In some markets Germany, the machine gained a strong foothold as a small business machine for CAD and desktop publishing work. Thanks to its built-in MIDI ports, the ST enjoyed success for running music-sequencer software and as a controller of musical instruments among amateurs and well-known musicians alike; the ST was superseded by the Atari STE, Atari TT, Atari MEGA STE, Falcon computers. The Atari ST was born from the rivalry between home-computer makers Atari, Inc. and Commodore International. Jay Miner, one of the original designers for the custom chips found in the Atari 2600 and Atari 8-bit family, tried to convince Atari management to create a new chipset for a video game console and computer; when his idea was rejected, Miner left Atari to form a small think tank called Hi-Toro in 1982 and began designing the new "Lorraine" chipset. The company, renamed Amiga Corporation, was pretending to sell video game controllers to deceive competition while it developed a Lorraine-based computer.
Amiga ran out of capital to complete Lorraine's development, Atari, owned by Warner Communications, paid Amiga to continue development work. In return Atari received exclusive use of the Lorraine design for one year as a video game console. After one year Atari would have the right to add a keyboard and market the complete computer, designated the 1850XLD; as Atari was involved with Disney at the time, it was code-named "Mickey", the 256K memory expansion board was codenamed "Minnie". After leaving Commodore International in January 1984, Jack Tramiel formed Tramel Technology with his sons and other ex-Commodore employees and, in April, began planning a new computer; the company considered the National Semiconductor NS320xx microprocessor but was disappointed with its performance. This started the move to the 68000; the lead designer of the Atari ST was ex-Commodore employee Shiraz Shivji, who had worked on the Commodore 64's development. Atari in mid-1984 was losing about a million dollars per day.
Interested in Atari's overseas manufacturing and worldwide distribution network for his new computer, Tramiel negotiated with Warner in May and June 1984. He bought Atari's Consumer Division in July; as executives and engineers left Commodore to join Tramiel's new Atari Corporation, Commodore responded by filing lawsuits against four former engineers for theft of trade secrets. The Tramiels did not purchase the employee contracts when they bought the assets of Atari Inc. so one of their first acts was to interview Atari Inc. employees to decide whom to hire at what was a brand new company. This company was called TTL renamed to Atari Corp. At the time of the purchase of Atari Inc's assets, there were 900 employees remaining from a high point of 10,000. After the interviews 100 employees were hired to work at Atari Corp. At one point a custom sound processor called AMY was a planned component for the new ST computer design, but the chip needed more time to complete, so AMY was dropped in favor of an off-the-shelf Yamaha sound chip.
It was during this time in late July/early August that Leonard Tramiel discovered the original Amiga contract, which required Amiga Corporation to deliver the Lorraine chipset to Atari on June 30, 1984. Amiga Corp. had sought more monetary support from investors in spring 1984. Having heard rumors that Tramiel was negotiating to buy Atari, Amiga Corp. entered into discussions with Commodore. The discussions led to Commodore wanting to purchase Amiga Corporation outright, which Commodore believed would cancel any outstanding contracts, including Atari's. Instead of Amiga Corp. delivering Lorraine to Atari, Commodore delivered a check of $500,000 to Atari on Amiga's behalf, in effect returning the funds Atari invested into Amiga for the chipset. Tramiel countersued Amiga Corp. on August 13, 1984. He sought an injunction to bar Amiga from producing anything with its technology. At Commodore, the Amiga team was in limbo during the summer of 1984 because of the lawsuit. No word on the status of the chipset, the Lorraine computer, or the team's fate was known.
In the fall of 1984, Commodore informed the team that the Lorraine project was active again, the chipset was to be improved, the operating system developed, the hardware design completed. While Commodore announced the Amiga 1000 with the Lorraine chipset in July 1985, the delay gave Atari, with its ma
Byte was an American microcomputer magazine, influential in the late 1970s and throughout the 1980s because of its wide-ranging editorial coverage. Whereas many magazines were dedicated to specific systems or the home or business users' perspective, Byte covered developments in the entire field of "small computers and software," and sometimes other computing fields such as supercomputers and high-reliability computing. Coverage was in-depth with much technical detail, rather than user-oriented. Byte started in 1975, shortly after the first personal computers appeared as kits advertised in the back of electronics magazines. Byte was published monthly, with an initial yearly subscription price of $10. Print publication ceased in 1998 and online publication in 2013. In 1975 Wayne Green was the editor and publisher of 73 and his ex-wife, Virginia Londner Green was the Business Manager of 73 Inc. In the August 1975 issue of 73 magazine Wayne's editorial column started with this item: The response to computer-type articles in 73 has been so enthusiastic that we here in Peterborough got carried away.
On May 25th we made a deal with the publisher of a small computer hobby magazine to take over as editor of a new publication which would start in August... Byte. Carl Helmers published a series of six articles in 1974 that detailed the design and construction of his "Experimenter's Computer System", a personal computer based on the Intel 8008 microprocessor. In January 1975 this became the monthly ECS magazine with 400 subscribers; the last issue was published on May 12, 1975 and in June the subscribers were mailed a notice announcing Byte magazine. Carl wrote to another hobbyist newsletter, Micro-8 Computer User Group Newsletter, described his new job as editor of Byte magazine. I got a note in the mail about two weeks ago from Wayne Green, publisher of'73 Magazine' saying hello and why don't you come up and talk a bit; the net result of a follow up is the decision to create BYTE magazine using the facilities of Green Publishing Inc. I will end up with the editorial focus for the magazine. Virginia Londner Green had returned to 73 in the December 1974 issue and incorporated Green Publishing in March 1975.
The first five issues of Byte were published by Green Publishing and the name was changed to Byte Publications starting with the February 1976 issue. Carl Helmers was a co-owner of Byte Publications; the first four issues were produced in the offices of 73 and Wayne Green was listed as the publisher. One day in November 1975 Wayne came to work and found that the Byte magazine staff had moved out and taken the January issue with them; the February 1976 issue of Byte has a short story about the move. "After a start which reads like a romantic light opera with an episode or two reminiscent of the Keystone Cops, Byte magazine has moved into separate offices of its own." Wayne Green was not happy about losing Byte magazine so he was going to start a new one called Kilobyte. Byte trademarked KILOBYTE as a cartoon series in Byte magazine; the new magazine was called Kilobaud. There was competition and animosity between Byte Publications and 73 Inc. but both remained in the small town of Peterborough, New Hampshire.
Articles in the first issue included Which Microprocessor For You? by Hal Chamberlin, Write Your Own Assembler by Dan Fylstra and Serial Interface by Don Lancaster. Advertisements from Godbout, MITS, Processor Technology, SCELBI, Sphere appear, among others. Early articles in Byte were do-it-yourself electronic or software projects to improve small computers. A continuing feature was Ciarcia's Circuit Cellar, a column in which electronic engineer Steve Ciarcia described small projects to modify or attach to a computer. Significant articles in this period included the "Kansas City" standard for data storage on audio tape, insertion of disk drives into S-100 computers, publication of source code for various computer languages, coverage of the first microcomputer operating system, CP/M. Byte ran Microsoft's first advertisement, as "Micro-Soft", to sell a BASIC interpreter for 8080-based computers. In spring of 1979, owner/publisher Virginia Williamson sold Byte to McGraw-Hill, she became a vice president of McGraw-Hill Publications Company.
Shortly after the IBM PC was introduced, in 1981, the magazine changed editorial policies. It de-emphasized the do-it-yourself electronics and software articles, began running product reviews, it continued its wide-ranging coverage of hardware and software, but now it reported "what it does" and "how it works", not "how to do it". The editorial focus remained on home and personal computers). By the early 1980s Byte had become an "elite" magazine, seen as a peer of Rolling Stone and Playboy, others such as David Bunnell of PC Magazine aspired to emulate its reputation and success, it was the only computer publication on the 1981 Folio 400 list of largest magazines. Byte's 1982 average number of pages was 543, the number of paid advertising pages grew by more than 1,000 while most magazines' amount of advertising did not change, its circulation of 420,000 was the third highest of all computer magazines. Byte earned $9 million from revenue of $36.6 million in 1983, twice the average profit margin for the magazine industry.
It remained successful while many other magazines failed in 1984 during economic weakness in the computer industry. The October 1984 issue had about 300 pages of ads sold at an average of $6,000 per page. From 1975 to 1986 Byte covers featured the artwork of Robert Tinney. Thes
