After years and years of interest in this, way back to
the sci am
'Ameteur Scientist' articles, I am beginning this project.
I have a unique and amazing resource, I work for a semiconductor
company in test engineering, and we use tons of those little TO-5
Teledyne relays in our IC test boards. I have scavenged >1000 or so
for the project, so its not going to be a giant machine like Harry

Have you read "The Computer - My Life" by Konrad Zuse (New York:
Springer Verlag, 1993. ISBN 0-387-56453-5)? Mostly historical /
autobiographical, but some good technical bits on the evolution of relay
logic as Zuse's designs got more mature. Interesting how the number of
relays per bit he needed in his adder circuit got less and less...
