I was in the computer club at UC Berkeley in 1975, and we had no hardware
at that time.  Later, we got two PDP-5's and after that a Honeywell
(DDP-350 ?).  One of the PDP-5's had a homebrew fast/slow switch on the
front panel, for varying the speed of the clock.  I guess you had a
choice between fast answers and correct answers.
