Altair

A microcomputer kit introduced in late 1974 from Micro Instrumentation and Telemetry Systems (MITS). It sold for USD $400 and used an 8080 microprocessor. In 1975, it was packaged with the Microsoft MBASIC interpreter written by Paul Allen and Bill Gates. Although computer kits were advertised earlier by others, an estimated 10,000 Altairs were sold, making it the first commercially successful microcomputer. See SCELBI 8H.
