Since the HP-80 was introduced on February 1, 1973 and the HP-70 was introduced on August 1, 1974, which machine would you have been using in 1972? Just askin'....
Thanks,

Little update to say that the 50g has run for thousand of hours as timer / stopwatch (weighted with value). I think I never let it run for so long for anything else (as the stopwatch on a 50g is a busy wait, there are no easy interrupts)

I think we should also add to the list:
The HP-01 calculator has a stopwatch.
Also the "new ACT" HP-21E, HP-22E, HP-25E, HP-27E, HP-29E, HP-67E .... and the "Woodstock Low Power".
