Altair 8800 Goes on Sale
December 19, 1974
Micro Instrumentation and Telemetry Systems, otherwise known as MITS, begins selling the Altair 8800 microcomputer kit. As the base computer used toggle switches for input and LEDs for output, it was far from a personal computer as we know it today. However, it is one of the most important computers in history, for it inspired the first generation of entrepreneurs that created the personal computer industry. After the Altair 8800 appeared on the cover of Popular Electronics magazine in January 1975, MITS was flooded with orders. Expecting to sell at most 800 units, MITS sold over 5,000 units by August of 1975.
