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 will develop into an educational platform

December 25, 2016 - The start of laying out the cardboard logic chips ( might as well call them very large chips or VLC's )

I will be running out of diodes before the end of this and the dmux build but at least I will get started. The logic is very basic and will end up being modified by the time I am finished. Logisim likes the circuit so far.

You can get a thousand diodes for a few bucks these days... it just requires a bit of patience for the delivery :-)
