 The "Sac State 8008" was possibly the first true microcomputer, with a disk operating system built with IBM Basic assembly language in PROM, all driving a color display, hard drive, keyboard, modem, audio/paper tape reader and printer.The project started in the spring of 1972, and with key help from Tektronix the system was fully functional a year later.Bill assisted Intel with the MCS-8 kit and provided key input to the Intel 8080 instruction set, which helped make it useful for the industry and hobbyists.
