I remember writing programs for on of these to solve a

it loaded the data from the metal tape( sometimes it needed to be
rebooted ).
I'd love to find one of these. I alway wanted to see how they
dealed with
the different speeds of the metal tape and the memory. There was no
exact speed control on the metal tape. It just ran from the spool
speed
with no capstan.
I'd imagine they just used a phase-locked loop for clock recovery
and clocked the data into the machine asynchronously. Is it more
complex than that?
