WThe Acorn Atom is a home computer made by Acorn Computers Ltd from 1980 to 1982, when it was replaced by the BBC Micro. The Micro began life as an upgrade to the Atom, originally known as the Proton.
WThe 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 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.
WThe Apple II is an 8-bit home computer and one of the world's first highly successful mass-produced microcomputer products. It was designed primarily by Steve Wozniak; Steve Jobs oversaw the development of the Apple II's foam-molded plastic case and Rod Holt developed the switching power supply. It was introduced by Jobs and Wozniak at the 1977 West Coast Computer Faire and marks Apple's first launch of a personal computer aimed at a consumer market—branded toward American households rather than businessmen or computer hobbyists.
WCorvette was an 8-bit personal computer in the USSR, created for Soviet schools in 1980s. The first device was a homemade computer, created in 1985 by employees of the Moscow State University for their purposes. The first description was made in the magazine «Microprocessor tools and systems». The PC was named "ПК 8001" (21.08.1985).
WThe IMSAI 8080 was an early microcomputer released in late 1975, based on the Intel 8080 and later 8085 and S-100 bus. It was a clone of its main competitor, the earlier MITS Altair 8800. The IMSAI is largely regarded as the first "clone" microcomputer. The IMSAI machine ran a highly modified version of the CP/M operating system called IMDOS. It was developed, manufactured and sold by IMS Associates, Inc.. In total, between 17,000 and 20,000 units were produced from 1975 to 1978.
WThe TRS-80 Micro Computer System is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their RadioShack stores. The name is an abbreviation of Tandy/RadioShack, Z80 microprocessor. It is one of the earliest mass-produced and mass-marketed retail home computers.
WThe RadioShack TRS-80 Color Computer is a line of home computers developed and sold by Tandy Corporation. Despite sharing a name with the earlier TRS-80, the Color Computer is a radical departure with its Motorola 6809E processor rather than a Zilog Z80. The Color Computer line is not compatible with software made for the earlier TRS-80.
