I suppose you might also include some Strowger switches for address
decoding...
Back when I was in high school (a very long time ago), a fellow built a
tic-tac-toe "computer" using stepping relays and other telephone gear,
including a rotary dial where one input one's move. (only 9 possibilities,
so that was convenient). The contraption would make its own move in
response. Readout was a 3x3 grid of 25W incandescent lamps.
It was fun to watch.
