This is the fifth part of a series of posts detailing steps required to get a simple Z80 based computer running, facilitated by a Teensy microcontroller. It’s a bit of fun, fuzing old and new hobbyist technologies. See Part 1, Part 2, Part 3 and Part 4 if you’ve missed them. At the moment, whilst running slowly due to the lock-step synchronous nature of the clock driving the Z80 from the Teensy, we do have a fairly well spec’d out little machine. So, in this fairly short post (it was sh...
