Altair 8800, MITS, Cromemco, Sol-20, Apple, Kim, TRS-80, Commodore, ... .. many! Some were based upon the 8080, others the 6502. My first, c1971, was based on the 8008, a predecessor of the 8080. It was a re-programmed "smart terminal" with an I/O selectric and optical paper tape reader. Audio tape on my next machine, a Sol-20, was a big improvement :-) Google for "first personal computer".
