THE MODEL THAT INSPIRED GATES AND ALLEN TO FORM MICROSOFT.
MITS ALTAIR 8800 holds the distinction of being the first microcomputer to catch on with the hobbyist market. It was originally offered in kit form for $439 or assembled for $621. Bill Gates, then in his Sophomore year at Harvard, and Paul Allen came across the December 1974 issue of Popular Electronics which featured the Altair on the cover and decided to join the computer revolution by writing a BASIC interpreter that would run on Altair's Intel 8080 microprocessor. "It would become the first commercial native high-level programming language for a microprocessor. And it would launch the personal computer software industry" (Isaacson p 332).
This appears to be a purpose-built by a professional with a pair of custom wire-wrap CPU boards. An interesting example. Isaacson. The Innovators. NY: [2014].
