- 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.
It took a lot of courage for him to befriend me in front of Hitler… You can melt down all the medals and cups I have and they wouldn’t be a plating on the 24-karat friendship I felt for Lutz Long at that moment.
