"I'm a programmer, the CPU is a mystic black box that gets fed instructions. I'm trying to learn and work out what the CPU really does. Here I build a system to control and watch the Z80's functions. This was inspired by Ben Eater's 6502 and 8Bit CPU videos, and is what I based my Arduino code on."
