Building a small computer, powered by a Z80 processor. Currently I'm in the state where I have a Z80 CPU hooked up to an Arduino (mega). The software running on the Arduino fakes RAM and hardware I/O so I can write simple programs in Z80 assembly language and test it. I've also managed to get BASIC running on it. The next step is to actually build a real circuit with serial I/O and real RAM/EPROM hardware so it will be standalone. |
