Like the DEC PDP-8, this is a 12-bit machine, but instead of the diode-transistor logic of the DEC, the substantially smaller Q2 uses a simple NMOS approach.

We've actually already seen one completely home-built 8-bit computer but, while Jake Eisenmann wasn't afraid to show off his creation, Kyle Hovey is actually inviting us along for the ride. The ...
