Information: - Atari is a corporate and brand name owned by several entities since its inception in 1972, currently by Atari Interactive, a subsidiary of the French publisher Atari, SA (ASA). The original Atari, Inc. founded in 1972 by Nolan Bushnell and Ted Dabney was a pioneer in arcade games, home video game consoles, and home computers. The company's products, such as "Pong" and the Atari 2600, helped define the electronic entertainment industry from the 1970s to the mid-1980s. - A minicomputer, or colloquially mini, is a class of smaller computers that developed in the mid-1960s and sold for much less than mainframe and mid-size computers from IBM and its direct competitors. In a 1970 survey, the "New York Times" suggested a consensus definition of a minicomputer as a machine costing less than , with an input-output device such as a teleprinter and at least four thousand words of memory, that is capable of running programs in a higher level language, such as Fortran or BASIC. The class formed a distinct group with its own software architectures and operating systems. Minis were designed for control, instrumentation, human interaction, and communication switching as distinct from calculation and record keeping. Many were sold indirectly to Original Equipment Manufacturers (OEMs) for final end use application. During the two decade lifetime of the minicomputer class (19651985), almost 100 companies formed and only a half dozen remained. - Home computers were a class of microcomputers entering the market in 1977, and becoming common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single nontechnical user. These computers were a distinct market segment that typically cost much less than business, scientific or engineering-oriented computers of the time such as the IBM PC, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporaneous business computers. Their most common uses were playing video games, but they were also regularly used for word processing, doing homework, and programming. - The Educator 64 , also known as the PET 64 and Model 4064 , was a microcomputer made by Commodore Business Machines in 1983 . It was sold to schools as a replacement for aging Commodore PET systems . Schools were reluctant to adopt the Commodore 64 '' breadbox '' design due to theft or vandalism of the smaller , more exposed components . The 4064 designation followed in line with the PET 's 4008 , 4016 and 4032 models as a 64kB 40 - column model . The innards of the Educator 64 were refurbished Commodore 64 motherboards and monochromatic green monitors . The area above the keyboard contained a quick reference card for BASIC 2.0 and Commodore DOS commands . The only differences between the Educator 64 and the other 64 models were the graphics capabilities , the built - in speaker , the sound amplifier with volume control , the 1/8 - inch mini-jack for mono sound output to headphones , the internal power supply , and the keyboard which is missing the color abbreviations imprinted on the front edge of the number keys . The Educator 64 retained the ability to display shades of green , while the PET 64 and 4064 were monochrome - only . Though the PET 4008/4016/4032 computers had cases made entirely of metal , only the Educator 64 's base was metal -- the upper case was made of thick plastic . The Educator 64 was not sold in great numbers . It suffered from its monochrome display - many 64 titles assumed the availability of color . And , by that time , the US education market was firmly in Apple 's grasp . - The VIC-20 (Germany: VC-20; Japan: VIC-1001) is an 8-bit home computer that was sold by Commodore Business Machines. The VIC-20 was announced in 1980, roughly three years after Commodore's first personal computer, the PET. The VIC-20 was the first computer of any description to sell one million units. - The TRS-80 Micro Computer System (TRS-80; later known as the Model I to distinguish it from successors) is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of "Tandy/Radio Shack, Z-80 microprocessor". It was one of the earliest mass-produced personal computers. - A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory, and minimal input/output (I/O) circuitry mounted on a single printed circuit board. Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense). - IBM System z (officially "IBM z Systems") is a family name used by IBM for all of its mainframe computers. In 2000, IBM renamed the existing System/390 to "IBM eServer zSeries" with the "e" depicted in IBM's red trademarked symbol, but because no specific machine names were changed for System/390, the zSeries name in common use refers only to the z900 and z990 generations of mainframes. In April 2006, with another generation of products, the official family was changed to IBM System z, which now includes both older "IBM eServer zSeries" models, the IBM System z9 models, the IBM System z10 models, and the newer IBM zEnterprise models. - Commodore International (or Commodore International Limited) was a North American home computer and electronics manufacturer. Commodore International (CI), along with its subsidiary Commodore Business Machines (CBM), participated in the development of the homepersonal computer industry in the 1970s and 1980s. The company developed and marketed one of the world's best-selling desktop computers, the Commodore 64 (1982) and released its Amiga computer line in July 1985. - The Commodore 64, also known as the C64, C-64, C= 64, or occasionally CBM 64 or VIC-64 in Sweden, is an 8-bit home computer introduced in January 1982 by Commodore International. It is listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 10 and 17 million units. Volume production started in early 1982, marketing in August for . Preceded by the Commodore VIC-20 and Commodore PET, the C64 took its name from its of RAM. It had superior sound and graphical specifications compared to other earlier systems such as the AppleII and Atari 800, with multi-color sprites and a more advanced sound processor. - The IBM System/360 introduced byte-addressable memory with 8-bit bytes, as opposed to bit-addressable or decimal digit-addressable or word-addressable memory, although its general purpose registers were 32 bits wide, and addresses were contained in the lower 24 bits of those addresses. Different models of System/360 had different internal data path widths; the IBM System/360 Model 30 (1965) implemented the 32-bit System/360 architecture, but had an 8 bit native path width, and performed 32-bit arithmetic 8 bits at a time. - The Commodore PET (Personal Electronic Transactor) is a line of home/personal computers produced starting in 1977 by Commodore International. A top-seller in the Canadian and United States educational markets, it was Commodore's first full-featured computer, and formed the basis for their entire 8-bit product line, including the Commodore 64. The first model, which was named the PET 2001, was the third personal computer ever made available to retail consumers, after the Apple II and TRS-80.
