If we are reminiscing I started on an Elliot 803 in the 60s.  It had a
processor clock of 1kHz I think (that's kiloHz) with a loudspeaker
pulsed from the instruction register if I remember correctly, so when
running a program that you knew well, you could tell where it was by
the sounds it made.  We used it, amongst other things, for designing
automobile alternators.  The program used to take a day or so to run.
