Z80 Breadboard Construction Labs Schematic Lab #0 Lab #1 Lab #2 Lab #3 Documentation Lab #0 Lab #1 Lab #2 Lab #3 These Z80 Labs start with as few as 3 to 5 chips, and allow observation of very basic CPU activity. Clock cycles for the Z80 can be extremely slow, and thereby can be used to a distinct advantage in comprehending what is and should be happening during memory cycle fetch and decode, and I/O activity requests.
