The First Microcomputer: The Q1

Quiz time, what was the first commercially available microcomputer? The Altair 8800? Something obscure like the SCELBI? The Mark-8 kit? 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. Later revisions used the Z80 processor, which is the model pictured above that [The Byte Attic] has in his possession. It’s a beautiful little machine, with a striking orange plasma display.

The irony is that this machine is almost entirely forgotten about. The original unit may have looked more like a typewriter, pictured here. If you have any first hand knowledge, or especially software, documentation, or surviving hardware bits, make sure to check in to add to the knowledge pool about this amazing little machine.

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. It seems that Daniel Alroy’s work on this machine literally kicked off the microcomputer revolution, and it’s been missing from our computer lore for too many years. We’re very hopeful to see more of this story come together, and the history of the Q1 fully recovered.

And if retro hardware is your jam, we’ve got you covered, including among others, the parallel story about the first microprocessor.
