If you’re interested in 1960s relay computer circuits, take a look at this Minivac 601 Simulator I just released!
~2 years of work on and off. Simulating electricity wasn’t as easy as I originally thought :)
Cheers!

Did you know famous mathematician Claude Shannon invented a tiny educational computer which he licensed to my grandfather and a friend for an edtech startup they eventually sold to RadioShack?
