First printed word for IO - April 11, 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.

Finally have been able to get IO to print out its first word. The home made opto-couplers had a little light leakage issue near the leds but sealed that end off with black silicone and now all of the circuit is working as desired :-)

Congrats! now i know if i ever have to type out something but don't want to do it myself, if i find a shit ton of brass fasteners and cardboard, i'll be set. XD that looks pretty sweet!

Thanks, however I think you might forget what you want to type by the time you gather all that cardboard and brass ;-)

No doubt my man, like I said when U began this journey, this is the most original and interesting project here IMO :)

Like I was telling Jez @Morning.Star today, I keep developing all the outer circuits but the Control Unit Is the main event and needs to be worked on very soon :-) But for now I am a proud papa as my child just said its first word today :-D
