Re:Ask HN: What is your hardware side project?

(#20765818)
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.
