I'm back again to the breadboard for this last module, as the work of soldering dozens of wires on the universal PCB was huge.

So I managed to make the PC and Memory module on a breadboard and run a simple program, with conditional and unconditional jumps:

The program loads the 32 value into A register and increments it until pass 255, then stops.

Thanks for reading.
