List of Early Microcomputers - Complete Microcomputers

Complete Microcomputers

A number of complete microcomputers were offered even before kits became popular, dating to as far back as 1973. For some time there was a major market for assembled versions of the Altair 8800, a market that grew significantly through the late 1970s and into the early 1980s. The introduction of three computers aimed at personal users in 1977, the Radio Shack TRS-80, Apple II, and Commodore PET, significantly changed the market and led to the home computer revolution.

• Datapoint 2200 of 1970 (shipping 1971) was the first machine designed to use a microprocessor, but when Intel could not deliver the 8008 in time, they released the machine using discrete logic.
• MicroSystems International's CPS-1, using a locally produced microprocessor based on the design of the Intel 4004. First built in 1972, a small number shipped in early 1973.
• Micral N (1973) was the earliest commercial, non-kit personal computer based on a microprocessor (the Intel 8008)
• MCM/70 was a 1974 Intel 8008-based design, primarily designed to run APL. According to the IEEE Annals of Computer History, the MCM/70 is the earliest commercial, non-kit personal computer.
• Processor Technology's Sol-20, offered both as kit and assembled, but the vast majority were sold assembled
• ECD Micromind, introduced 1977 MOS Technology 6512 (6502 w/ external clock). Prototypes only.
• MPT8080 Microtutor, an Intel 8080–based microprocessor trainer introduced 1977. As recently as 2008, it remained in academic use. As of 2011, the MPT8080 was still available for sale.
• Tesla PMI-80
• Ohio Scientific Model 500, 1978, 6502
• Explorer/85 8085, 1979
