Speed control for IO - January 30, 2018

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.

I have added a very basic speed control to the master clock circuit.

I think this is my favourite project here, I love the sheer lunacy implied in building a cardboard computer, but there it is, a wonder to behold.  I'm always showing friends these videos too.  Great to see it continue to develop, keep up the good work!  ;)

Thanks Martian :-) However I keep getting distracted from working on the instruction set and I need a "No Smoking" sign around all the cardboard ;-)
