Good morning Fedor and thank you for the follow and like of #Light Logic  :-)

  Are you sure? yes | no

Thank you Mark for my first bit!

Funny coincidence - I'm currently working on 4-bit CPU, just like your Cardboard Computer (although it involves ICs and not discrete-part gates). I'll post about it soon, so stay tuned!

  Are you sure? yes | no

Dr. Cockroach wrote 10/09/2018 at 11:25 • point

That sounds great and I will be looking forward to it :-)
