What possessed me to do this?
Inspiration for this project came from two sources.
One is the effort underway at the National Museum of Computing in
Bletchley Park to build a replica of the EDSAC, one of the earliest
stored-program computers, built at Cambridge University in the late
The other is a series of videos by Ben Eater about the construction of
a simple computer on breadboards from 74 series logic chips.
Put these two things together, add in a hankering to do something with
hardware and a pile of parts burning a hole in the bottom of my junk
box, and the conclusion is obvious. I need to build a breadboard
implementation of the EDSAC!
