What I do not like is using a uC that is almost as capable as the whole board as part of it. I know, you have to take a pragmatic approach… but feels like cheating… idk. | ||

The Z80-MBC (the original breadboard version [0]) was actually the second Z80 computer I built. I first tried out one of the Grant Searle designs [1] on a breadboard, and it worked!... for literally 8 seconds, then the single ACIA chip I had waited weeks to get died for no reason. But I didn't have any way to debug what was wrong. It also didn't help that I didn't have many EEPROMs or an EEPROM programmer at the time, but the ATMega32A can be programmed with an ordinary Arduino.
