well this is disappointing..."binary toggles" had me picturing a single 3-way toggle switch where you manually entered ones and zeroes.

  That is exactly what is going on but you don't need 3 way toggle. Down is 0 and up is 1, you load all of the values in like a shift register but in parallel, then write/act upon them.

    Right...but surely you see how that's different from what I described.

    Yes the data bits were 2-way toggles, but one important switch was a 3-way toggle: the Examine (press down) and Deposit (press up) switch.

      On the 11/70, Deposit was the only switch that toggled up (other than the light test switch). That is a nice safety feature so you don't accidentally toggle Continue or other action switches.
