I didn’t like the first revision of the Schematic so I redid the whole thing. I came across a Z80 Trainer made by Dr. Baker and used that as the basis of the new Schematic. I also used the circuit for the VT132 Project for a Terminal VGA and USB Keyboard.
These are not final. I need to review these and make sure everything is in the right order. I also need to import the S-100 BUS.
