- I’ve been reverse-engineering the Z-80 processor, using images from the Visual 6502 team. One interesting thing about the Z-80’s silicon is it uses complex gates with multiple inputs and multiple levels of logic. It also implements an XOR gate with an unusual pass-transistor circuit. I thought it would be interesting to examine these gates at the silicon level and show how they work.
