A project log for The Cardboard Computer - IO is my name

My goal is a 4-bit CPU using recycled cardboard substrate and Diode Transistor Logic. This is an educational platform for me.

Just when I think I am on a roll with IO then along comes Murphy Lol. The ALU logic levels for a zero are not what the MUX wants so I am patching in four non-inverting buffers to set things right. The Mux is happier now. Just need to mount the new gates to IO :-)
