I beleive the Pilot Ace computer had a telephone dial on the operate
console which was used as some kind of single-stepping clock. You could
generate 1 to 10 clock pulses in the obvious way.
I'm not sure abut the Pilot ACE. The picture I have does not have the
resolution to show if there is a telephone dial on the console. I do
however know that the DEUCE, developed from the Pilot ACE and ACE did
have a dial.
ISTR that the Ferranti Pegasus has one also, and the EDSAC as has
already been mentioned.
