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...
I always loved his vertually zero delay carry. At least
it was zero for relays. It was something that one
would not think of just looking at a single bit or
even normal logic of digital stuff.
