"Core Memory"

I bought this very cool book from the Computer History Museum, that's the KENBAK-1.

 

This is an Arduino-based emulation of the KENBAK-1, considered by some to be the first "personal computer". It was first advertised for sale in the September 1971 issue of Scientific American (forty years ago!).

See the set.

See the videos.

Get the Arduino sketch from here.
