I shared this previously on a Kenbak-1 facebook page but thought I'd share it here too.
This implements a 1-dimensional cellular automata and prints it by wiring photoresistors to the keyboard connector on an electrical typewriter and flashing certain bits on the uKenbak-1 to press 'a', space, or return.
It has no practical value but it was enjoyable to create. Thanks for creating these replica/emulators, it has given me insights into machine coding that I never had previously.
