Commodore 64

The Commodore 64, also known as the C64 or the CBM 64, 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 10 and 17 million units. Volume production started in early 1982, marketing in August for US$595. Preceded by the Commodore 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.

Apple Lisa

The Apple Lisa is a desktop computer developed by Apple, released on January 19, 1983. It was one of the first personal computers to offer a graphical user interface (GUI) in a machine aimed at individual business users. Development of the Lisa began in 1978, and it underwent many changes during the development period before shipping at the very high price of US $9,995 with a 5 MB hard drive. The high price, relatively low performance and unreliable Apple FileWare, or "Twiggy" floppy disks, led to poor sales, with only 100,000 units sold. However, these sales generated about $1 bn in revenue, which would later help keep the company afloat amidst an ongoing crisis.

Altair 8800

The Altair 8800 is a microcomputer designed in 1974 by MITS and based on the Intel 8080 CPU. Interest grew quickly after it was featured on the cover of the January 1975 issue of Popular Electronics, and was sold by mail order through advertisements there, in Radio-Electronics, and in other hobbyist magazines. The designers hoped to sell a few hundred build-it-yourself kits to hobbyists, and were surprised when they sold thousands in the first month. The Altair also appealed to individuals and businesses that just wanted a computer and purchased the assembled version. The Altair is widely recognized as the spark that ignited the microcomputer revolution as the first commercially successful personal computer. The computer bus designed for the Altair was to become a de facto standard in the form of the S-100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.

Amiga

The Amiga is a family of personal computers introduced by Commodore in 1985. The original model was part of a wave of 16 and 32 bit computers that featured 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio over 8-bit systems. This wave included the Atari ST—released the same year—Apple's Macintosh, and later the Apple IIGS. Based on the Motorola 68000 microprocessor, the Amiga differed from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS.

Apple II

The Apple II is an 8-bit home computer, one of the first highly successful mass-produced microcomputer products, designed primarily by Steve Wozniak. It was introduced in 1977 at the West Coast Computer Faire by Jobs and was the first consumer product sold by Apple Computer, Inc. It is the first model in a series of computers which were produced until Apple IIe production ceased in November 1993. The Apple II marks Apple's first launch of a personal computer aimed at a consumer market – branded towards American households rather than businessmen or computer hobbyists.

ZX81

The ZX81 is a home computer that was produced by Sinclair Research and manufactured in Dundee, Scotland by Timex Corporation. It was launched in the United Kingdom in March 1981 as the successor to Sinclair's ZX80 and was designed to be a low-cost introduction to home computing for the general public. It was hugely successful, and more than 1.5 million units were sold before it was discontinued. The ZX81 found commercial success in many other countries, notably the United States where it was initially sold as the ZX-81. Timex manufactured and distributed it under licence and enjoyed a substantial but brief boom in sales. Timex later produced its own versions of the ZX81 for the US market: the Timex Sinclair 1000 and Timex Sinclair 1500. Unauthorized clones of the ZX81 were produced in several countries.

Atari ST

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 widely 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 also the first with a cost-per-kilobyte of less than US$1.

Commodore VIC-20

The VIC-20 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.

Apple II series

The Apple II series is a family of home computers, one of the first highly successful mass-produced microcomputer products, designed primarily by Steve Wozniak, manufactured by Apple Computer, and launched in 1977 with the original Apple II. In terms of ease of use, features, and expandability, the Apple II was a major advancement over its predecessor, the Apple I, a limited-production bare circuit board computer for electronics hobbyists. Through 1988, a number of models were introduced, with the most popular, the Apple IIe, remaining relatively little changed into the 1990s. A 16-bit model with much more advanced graphics and sound, the Apple IIGS, was added in 1986. While compatible with earlier Apple II systems, the IIGS was in closer competition with the Atari ST and Amiga.

Atari 8-bit family

The Atari 8-bit family is a series of 8-bit home computers introduced by Atari, Inc. in 1979 and manufactured until 1992. All of the machines in the family are technically similar and differ primarily in packaging. They are based on the MOS Technology 6502 CPU running at 1.79 MHz, and were the first home computers designed with custom co-processor chips. This architecture enabled graphics and sound capabilities that were more advanced than contemporary machines at the time of release, and gaming on the platform was a major draw. Star Raiders is considered the platform's killer app.

BBC Micro

The British Broadcasting Corporation Microcomputer System, or BBC Micro, is a series of microcomputers and associated peripherals designed and built by the Acorn Computer company in the 1980s for the BBC Computer Literacy Project, operated by the British Broadcasting Corporation. Designed with an emphasis on education, it was notable for its ruggedness, expandability, and the quality of its operating system. An accompanying 1982 television series, The Computer Programme, featuring Chris Serle learning to use the machine, was also broadcast on BBC 2.

Commodore PET

The Commodore PET 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 presented to the public at the Winter Consumer Electronics Show in 1977.
