February 10, 2018 - Diode ROM test board

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.

Testing the logic for a diode ROM to be used on the Brainwarp entry panel. So far so good as it is working as expected. This test panel uses 2 bit addressing to select between 4 memory addresses with 4 bits each.

Just FYI... if you cut the leads shorter, the diodes will work fine and take up less space ;)

...yes, or course I'm being facetious, why do you ask? :P

  Are you sure? yes | no
