Returning to the Z80 ALU core implemented in relays. The first task is to redo the relay symbols. Kicads default generic relay shows the solenoid repelling the contacts, rather than attracting them. It's messing with my head.
In the image I've update the two symbols on the left. The rest are still defaults.
(PS Kicad only has a generic symbol for the single pole relay. I extended this to create the tow and three pole versions).
