The Commodore 64, also known as the C64, is an 8-bit home computer introduced in January 1982 by Commodore International. It has been listed in the Guinness World Records as the highest-selling single computer model of all time, with independent estimates placing the number sold between 12.5 and 17 million units. Volume production started in early 1982, marketing in August for US$595. Preceded by the VIC-20 and Commodore PET, the C64 took its name from its 64 kilobytes(65,536 bytes) of RAM. With support for multicolor sprites and a custom chip for waveform generation, the C64 could create superior visuals and audio compared to systems without such custom hardware.
Commodore International Corporation was a Bahamian home computer and electronics manufacturer with executive offices in the United States founded by Jack Tramiel and Irving Gould. Commodore International (CI), along with its subsidiary Commodore Business Machines (CBM), was a significant participant in the development of the home computer industry in the 1970s to early 1990s. In 1982, the company developed and marketed the world's second-best selling computer, the Commodore 64, and released its Amiga computer line in July 1985. Commodore was one of the world's largest personal computer manufacturers, with sales peaking in the last quarter of 1983 at $49 million.
VisiCalc is the first spreadsheet computer program for personal computers, originally released for the Apple II by VisiCorp on October 17, 1979. It is considered the killer application for the Apple II, turning the microcomputer from a hobby for computer enthusiasts into a serious business tool, and then prompting IBM to introduce the IBM PC two years later. More than 700,000 copies were sold in six years, and up to 1 million copies over its history.
The Amiga 600, also known as the A600, is a home computer introduced in March 1992. It is the final Amiga model based on the Motorola 68000 and the 1990 Amiga Enhanced Chip Set. A redesign of the Amiga 500 Plus, it adds the option of an internal hard disk drive and a PCMCIA port. Lacking a numeric keypad, the A600 is only slightly larger than an IBM PC keyboard, weighing approximately 6 pounds (2.72kg). It shipped with AmigaOS 2.0, which was considered more user-friendly than earlier versions of the operating system.
The Commodore Plus/4 is a home computer released by Commodore International in 1984. The "Plus/4" name refers to the four-application ROM-resident office suite ; it was billed as "the productivity computer with software built in".

Amiga software is computer software engineered to run on the Amiga personal computer. Amiga software covers many applications, including productivity, digital art, games, commercial, freeware and hobbyist products. The market was active in the late 1980s and early 1990s but then dwindled. Most Amiga products were originally created directly for the Amiga computer, and were not ported from other platforms.
Supersoft is a software and computer game developer and publisher founded in England in 1978. It was founded by Peter Calver and Pearl Wellard to develop and publish software primarily for the Commodore PET.
Microchess, sometimes written as MicroChess, is a chess program developed for the MOS Technology KIM-1 microcomputer by Peter R. Jennings in 1976, and published by his company Micro-Ware. The game plays chess against the human player at a beginner level, with the player entering moves via a keyboard and the computer responding, both in a custom chess notation. The game was ported to many other microcomputers such as the TRS-80, Apple II, Commodore PET, and Atari 8-bit computers by Micro-Ware and its successor company Personal Software between 1976 and 1980, with later versions featuring graphics and more levels of play. A dedicated hardware version of the game called ChessMate was produced by Commodore International in 1978, and the game's engine was licensed to Novag for its dedicated Chess Champion Mk II chess computer in 1979.
The history of the personal computer as a mass-market consumer electronic device began with the microcomputer revolution of the 1970s. A personal computer is one intended for interactive individual use, as opposed to a mainframe computer where the end user's requests are filtered through operating staff, or a time-sharing system in which one large processor is shared by many individuals. After the development of the microprocessor, individual personal computers were low enough in cost that they eventually became affordable consumer goods. Early personal computers – generally called microcomputers – were sold often in electronic kit form and in limited numbers, and were of interest mostly to hobbyists and technicians.
A personal computer, usually referred to as a PC, is a computer designed for individual use. It is typically used for tasks such as word processing, internet browsing, email, multimedia playback, and gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. The term home computer has also been used, primarily in the late 1970s and 1980s. The advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people in all countries.
Home computers were a class of microcomputers that entered the market in 1977 and became 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, non-technical 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 those running CP/M or 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 contemporary business computers. Their most common uses were word processing, playing video games, and programming.
Batteries Included was a computer software and hardware company based in the Toronto area. It developed products for the Apple II, Atari 8-bit computers, Atari ST, Commodore 64, and MS-DOS. The company was best known in the 1980s for its PaperClip word processor, which was available for the Atari 8-bit family and Commodore 64, and the DEGAS bitmap painting program for the Atari ST. Batteries Included was acquired by Electronic Arts in 1987.
Smoke Signal Broadcasting, Inc. (SSB), later known as Smoke Signal, was an American computer company founded in 1976 by Frederic Jerome "Ric" Hammond of Hollywood, California. The company earned its reputation by offering expansions for the Southwest Technical Products (SWTPC) 6800 microcomputer. It later manufactured its own line of computers, called the Chieftain. Though it remains little-known, Smoke Signal was an early and important manufacturer of multi-user computer systems.
Magic Desk was a planned series of productivity software by Commodore Business Machines for the Commodore 64. Only the first entry, Type and File, was ever released. It was introduced at the summer edition of the 1983 Consumer Electronics Show in June, slated for an August 31 release. Commodore developed the Magic Desk suite both in response to a perceived lack of productivity software for the Commodore 64 and to the graphical user interface of the Apple Lisa.
3D Microcomputers Wholesale and Distribution, Inc., often referred to as 3D Microcomputers or 3D Micro, was a computer company based in Markham, Ontario. The company was among the top five personal computer vendors in Canada in the mid-1990s.

Pronto Computers, Inc., was an American computer company based in Torrance, California, active from 1983 to 1987. During its brief existence, the company released a duo of IBM PC compatible computer systems and a family of high-spec graphics cards. Pronto's first product, the System 16, was widely lauded for its graphical prowess and industrial design; in 1983, I.D. magazine named it the best-designed product in the field of instrumentation and equipment. The System 16 was followed up with the Pronto Transportable Solution, a portable computer. Both it and the Pronto 16 ran the Intel 80186, a microprocessor seldom used in IBM PC compatibles. Pronto Computers went bankrupt shortly after the Black Monday financial crisis of 1987.
Apparat, Inc., was an American software developer, peripheral manufacturer, mail order company, and retailer active from 1978 to 1988 and primarily based in Denver, Colorado.
