Query: What was the first personal computer?
Using the narrow definition of "operated by one person", the first personal computer was the ENIAC which became operational in 1946. It did not meet further definitions of affordable or easy to use. The Bendix G15 of 1956 was intended for use without an operating staff, and several hundred were made; it was too costly to be personally owned, however.
Following the 1947 invention of the cathode-ray tube amusement device, the earliest known interactive electronic game as well as the first to use an electronic display, the first true video games were created in the early 1950s. Initially created as technology demonstrations, such as the "Bertie the Brain" and Nimrod computers in 1950 and 1951, video games also became the purview of academic research. A series of games, generally simulating real-world board games, were created at various research institutions to explore programming, human–computer interaction, and computer algorithms. These include "OXO" and Christopher Strachey's draughts program in 1952, the first software-based games to incorporate a CRT display, and several chess and checkers programs. Possibly the first video game created simply for entertainment was 1958's "Tennis for Two", featuring moving graphics on an oscilloscope. As computing technology improved over time, computers became smaller and faster, and the ability to work on them was opened up to university employees and undergraduate students by the end of the 1950s. These new programmers began to create games for non-academic purposes, leading up to the 1962 release of "Spacewar!" as one of the earliest known digital computer games to be available outside a single research institute.
Three other CPU chip designs were produced at about the same time: the Four-Phase Systems AL1, done in 1969; the MP944, completed in 1970 and used in the F-14 Tomcat fighter jet; and the Texas Instruments TMS-1000 chip, announced in September 17, 1971. Both the AL1 and the MP944 use several chips for the implementation of the CPU function. The TMS0100 chip was presented as a “calculator on a chip” with the original designation TMS1802NC. This chip contains a very primitive CPU and can only be used to implement various simple 4-function calculators. It is the precursor of the TMS1000, introduced in 1974, which is considered the first microcontroller i.e., a computer on a chip containing not only the CPU, but also ROM, RAM, and I/O functions. The MCS-4 family of 4 chips developed by Intel, of which the 4004 is the CPU or microprocessor, was far more versatile and powerful than the single chip TMS1000, allowing the creation of a variety of small computers for various applications.
The ' ("" - which means "small computer" - being a rather literal German translation of the English "microcomputer") is a clone of the Amstrad CPC built by East Germany's ' in October 1989. Although the machine included various substitutes and emulations of an Amstrad CPC's hardware, the machine is largely compatible with Amstrad CPC software. It is equipped with 64 KB memory and a CPC6128's firmware customized to the modified hardware, including an unmodified copy of Locomotive BASIC 1.1. The KC compact is the last 8-bit computer produced in East Germany.
That same year saw the release of the Magnavox Odyssey, the first home video game console which could be connected to a television set. The inventor, Ralph H. Baer, had initially had the idea in 1951 to make an interactive game on a television set. Unable to do so with the technological constraints at the time, he began work on a device that would attach to a television set and display games in 1966, and the "Brown Box", the last prototype of seven, was licensed to Magnavox to adapt and produce. They announced the console in May 1972, and it went on sale that September. The console and its games featured numerous innovations beyond being the first video game device for home consumers: it was the first game to use a raster-scan video display, or television set, directly displayed via modification of a video signal; it was also the first video gaming device to be displayed in a television commercial. It sold for US$100 and shipped with several games, including "Table tennis", which Bushnell had seen a demo of and which "Pong" had been based on. The Odyssey sold over 100,000 units in 1972, and more than 350,000 by the end of 1975, buoyed by the popularity of the table tennis game, in turn driven by the success of "Pong". "Pong" and the Odyssey kicked off a new era of video gaming, with numerous other competitors starting up in the video game industry as it grew in popularity.
Mary Allen Wilkes (born September 25, 1937 in Chicago, Illinois) is a former computer programmer and logic designer, most known for her work with the LINC computer, now recognized by many as the world's first "personal computer." Wilkes graduated from Wellesley College in 1959 where she majored in philosophy and theology. At that time she wanted to become a lawyer but was discouraged by friends and mentors because she was a woman. She sought work in the computer field partly because computer programming was a field that was open to women and partly because her geography teacher in the eighth grade had told her during a class discussion, "Mary Allen, when you grow up, you ought to be a computer programmer." She had no idea at the
time what that meant, but she never forgot it. She finally became an attorney in 1975.
In the Commodore world, GEOS was available on the Commodore 64 and Commodore 128. Later, a version was available for PCs running DOS. It could be used with a mouse or a joystick as a pointing device, and came with a suite of GUI applications. Commodore's later product line, the Amiga platform, ran a GUI operating system by default. The Amiga laid the blueprint for future development of personal computers with its groundbreaking graphics and sound capabilities. "Byte" called it "the first multimedia computer... so far ahead of its time that almost nobody could fully articulate what it was all about."
Throughout the rest of the 1960s, digital computer games were created by increasingly numerous programmers and sometimes sold commercially in catalogs. As the audience for video games expanded to more than a few dozen research institutions with the falling cost of computers, and programming languages that would run on multiple types of computers were created, a wider variety of games began to be developed. Video games transitioned into a new era in the early 1970s with the launch of the commercial video game industry in 1971 with the display of the coin-operated arcade game "Galaxy Game" and the release of the first arcade video game "Computer Space", and then in 1972 with the release of the immensely successful arcade game "Pong" and the first home video game console, the Magnavox Odyssey, which launched the first generation of video game consoles.
Thermal transfer printing was invented by SATO corporation, a Japanese company. They produced the world's first thermal transfer label printer, SATO M-2311, in 1981.The concept of a single-chip microprocessor CPU (central processing unit) was conceived in a 1968 meeting in Japan between Sharp engineer Tadashi Sasaki and an unnamed female software engineering researcher from Nara Women's College. He discussed the concept at a brainstorming meeting that was held in Japan. Sasaki attributes the basic invention to break the chipset of a calculator into four parts with ROM (4001), RAM (4002), shift registers (4003) and CPU (4004) to an unnamed woman, a software engineering researcher from Nara Women's College, who was present at the meeting. Sasaki then had his first meeting with Noyce in 1968. Sasaki discussed the microprocessor concept with Busicom and Intel in 1968, and presented the woman's four-division chipset concept to Intel and Busicom. This provided the basis for the single-chip microprocessor design of the Intel 4004. He was also involved in the development of the Busicom 141-PF desktop calculator which led to the 4004's creation. Sasaki thus played a key role in the creation of the first microprocessor.
Since the 18th century, women have developed scientific computations, including Nicole-Reine Lepaute's prediction of Halley's Comet, and Maria Mitchell's computation of the motion of Venus. The first algorithm intended to be executed by a computer was designed by Ada Lovelace who was a pioneer in the field. Grace Hopper was the first person to design a compiler for a programming language. Throughout the 19th and early-20th century, and up to World War II, programming was predominantly done by women; significant examples include the Harvard Computers, codebreaking at Bletchley Park and engineering at NASA.
Atari, Inc. was an American video game developer and video game console and home computer development company which operated between 1972 and 1984. During its years of operation, it developed and produced over 350 arcade, console, and computer games for its own systems, and almost 100 ports of games for home computers such as the Commodore 64. Atari began its operations by developing and producing some of the first arcade video games; the first commercial arcade video game, "Computer Space", was released in November 1971 by Atari founders Nolan Bushnell and Ted Dabney in partnership as Syzygy Engineering. The game in part marked the end of the early history of video games and the start of the rise of the commercial video game industry. After its founding in 1972, Atari released "Pong", believed to be the third arcade video game after "Computer Space" and a clone game and the first commercially successful arcade video game machine, and thereafter produced numerous arcade games, including video games and pinball machines.
In 1990, Microsoft introduced its office suite, Microsoft Office. The suite bundled separate productivity applications, such as Microsoft Word and Microsoft Excel. On May 22, Microsoft launched Windows 3.0, featuring streamlined user interface graphics and improved protected mode capability for the Intel 386 processor. Both Office and Windows became dominant in their respective areas.
October 1985's issue 10 looks at the new Amstrad CPC 6128; a new computer with a disk drive plus 128k of memory.
Released July 15, 1983, the Nintendo Entertainment System (NES) is an 8-bit video game console released by Nintendo in North America, South America, Europe, Asia, Oceania and Africa and was Nintendo's first home video game console released outside Japan. In Japan, it is known as the "Family Computer" (or "Famicom", as it is commonly abbreviated). Selling 61.91 million units worldwide, the NES helped revitalize the video game industry following the video game crash of 1983 and set the standard for subsequent consoles in everything from game design to business practices. The NES was the first console for which the manufacturer openly courted third-party developers. Many of Nintendo's most iconic franchises, such as "The Legend of Zelda" and "Metroid" were started on the NES. Nintendo continued to repair Famicom consoles in Japan until October 31, 2007, attributing the decision to discontinue support to an increasing shortage of the necessary parts.
Around the same time, Douglas Engelbart used computer screens both as input and output devices. In 1968, Ivan Sutherland, with the help of many students including Bob Sproull, created what was widely considered to be the first head-mounted display (HMD) system for use in immersive simulation applications. It was primitive both in terms of user interface and realism, and the HMD to be worn by the user was so heavy that it had to be suspended from the ceiling. The graphics comprising the virtual environment were simple wire-frame model rooms. The formidable appearance of the device inspired its name, The Sword of Damocles.
In 1972, the first commercially available video game console, the Magnavox Odyssey, had a light gun accessory, the Shooting Gallery. This was the first involvement of Nintendo in video games. According to Martin Picard in the "International Journal of Computer Game Research": "in 1971, Nintendo had -- even before the marketing of the first home console in the United States -- an alliance with the American pioneer Magnavox to develop and produce optoelectronic guns for the Odyssey (released in 1972), since it was similar to what Nintendo was able to offer in the Japanese toy market in 1970s".
Texas Instruments (TI), at the time the world's largest chip manufacturer, decided to enter the home computer market with the Texas Instruments TI-99/4A. Announced long before its arrival, most industry observers expected the machine to wipe out all competition – on paper its performance was untouchable, and TI had enormous cash reserves and development capability.
The chip design started in April 1970, when Federico Faggin joined Intel, and was completed under his leadership in January 1971. The first commercial sale of the fully operational 4004 occurred in March 1971 to Busicom Corp. of Japan for which it was originally designed and built as a custom chip. In mid-November of the same year, with the prophetic ad "Announcing a new era in integrated electronics", the 4004 was made commercially available to the general market. The 4004 was the first commercially available monolithic processor, fully integrated in one small chip. Such a feat of integration was made possible by the use of the then-new silicon gate technology for integrated circuits, originally developed by Faggin (with Tom Klein) at Fairchild Semiconductor in 1968, which allowed twice the number of random-logic transistors and an increase in speed by a factor of five compared to the incumbent MOS aluminum gate technology. Faggin also invented the bootstrap load with silicon gate and the “buried contact”, improving speed and circuit density compared with aluminum gate.
The Texas Instruments TI-99/4A is a home computer, released June 1981 in the United States at a price of $525 ($ adjusted for inflation). It is an enhanced version of the less successful TI-99/4 model, which was released in late 1979 at a price of $1,150 ($ adjusted for inflation). Both models include support for sprites and multi-channel sound, some of the first home computers to include such custom hardware, alongside the Atari 8-bit family also introduced in 1979.
In 1981, he wired together the backplanes of two DEC VAX-11/780's and made the first multi-CPU Unix computer, preceding DEC's dual processor VAX-11/782. The operating system was based on the 4.2 BSD kernel, and the modifications thus made eventually made it into the 4.3 BSD Unix release. At the beginning of the 4.3 BSD user manuals, Bill Joy wrote a special note of thanks to GHG for being courageous enough to put the multi-CPU kernel into a production environment before anyone else did. (However, the frequent crashes for a while inspired the writing of many humorous text files by the Purdue University Electrical Engineering student body, such as "The VAX had a Blowout", to be sung to the tune of London Bridge is Falling Down). The development of the Dual-CPU Unix system was the subject of Goble's Master's thesis.
The Intel 8008 was the world's first single-chip 8-bit CPU and, like the 4004, was built with p-channel SGT. The 8008 development was originally assigned to Hal Feeney in March 1970 but was suspended until the 4004 was completed. It was resumed in January 1971 under Faggin's direction utilizing the basic circuits and methodology he had developed for the 4004, with Hal Feeney doing the chip design. The CPU architecture of the 8008 was originally created by CTC, Inc., to power the Datapoint 2200 intelligent terminal.
In the mid-twentieth century, computers were extremely rare and used only by specialists. They were equipped with complicated interfaces comprehensible only to these select few. In 1968, Douglas Engelbart gave a demonstration which astonished executives at Xerox. They began work on what would eventually become the Xerox Alto. In 1973, Xerox completed work on the first personal computer, the Xerox Alto, which had a sophisticated graphical user interface (GUI) involving windows, icons, menus and a pointer. (WIMP) Unfortunately, the Xerox Alto, and its successor the Xerox Star were far too expensive for the average consumer, and suffered from poor marketing. In 1984 Apple Computer launched the Apple Macintosh, which was the first affordable and commercially successful personal computer to include a graphical user interface. The Macintosh was the second Apple Computer to ship with a graphical user interface, with the Apple Lisa being the first. In 1985, Microsoft released Microsoft Windows which bore a striking resemblance to both Macintosh, and to the Alto's interface. Windows eventually overtook Apple in the PC market to become the predominant GUI-based operating system.
Although mechanical examples of computers have existed through much of recorded human history, the first electronic computers were developed in the mid-20th century (1940–1945). These were the size of a large room, consuming as much power as several hundred modern personal computers (PCs).[1] Modern computers based on integrated circuits are millions to billions of times more capable than the early machines, and occupy a fraction of the space.[2] Simple computers are small enough to fit into small pocket devices, and can be powered by a small battery. Personal computers in their various forms are icons of the Information Age and are what most people think of as "computers". However, the embedded computers found in many devices from MP3 players to fighter aircraft and from toys to industrial robots are the most numerous.
ComputerLand was founded by William H. Millard. In 1974 he launched a company, IMS Associates, Inc., to build what was claimed to be the first truly integrated personal computers, sold as kits to hobbyists and the rapidly growing numbers of retailers (through small ads in "Popular Electronics"). The computer, the IMSAI 8080, may not have made Millard's fortune, but his resulting experiences with the inexperienced and under‑capitalized retailers did. In 1976 (at the same time as the Byte Shop was selling its first few Apples) he asked his Sales Director, Ed Faber (an ex‑IBM Manager), to start a new franchise operation, soon to become ComputerLand.
While Intel created the first commercially available microprocessor (Intel 4004) in 1971 and one of the first microcomputers in 1972, by the early 1980s its business was dominated by dynamic random-access memory chips. However, increased competition from Japanese semiconductor manufacturers had, by 1983, dramatically reduced the profitability of this market. The growing success of the IBM personal computer, based on an Intel microprocessor, was among factors that convinced Gordon Moore (CEO since 1975) to shift the company's focus to microprocessors and to change fundamental aspects of that business model. Moore's decision to sole-source Intel's 386 chip played into the company's continuing success.
The development of the micro-processor by Intel, (1971): The micro-processor represented a notable advance in the technology of integrated circuitry. A micro-processor miniaturized the central processing unit of a computer, which then made it possible for small machines to perform calculations that in the past only very large machines could do. Considerable technological innovation was needed before the micro-processor could actually become the basis of what was first known as a "mini computer" and then known as a "personal computer".
