According to [The Byte Attic], it was actually the Q1, based on the Intel 8008 processor. The first Q1 microcomputer was delivered in December of 1972, making it the first, as far as he can tell. It’s a beautiful little machine, with a striking orange plasma display. It’s an important milestone, and the development of the Q1 may have been a direct cause of Intel developing the more powerful 8080 microprocessor. We’re very hopeful to see more of this story come together, and the history of the Q1 fully recovered.
