Uhm....
We (Astronomical Dept. at Bonn University) had a VAX 11/780. An early
VAX 11/780, I've been told, so early that its memory controller could NOT
handle more than 4 MB of RAM. While we could have afforded 3rd-party
memory add-ons, we could not afford a 2nd memory controller.
Rwo evenings a week was AIPS evening... the evening the people using the AIPS
image processing system were _allowed_ to run it.
I used a different system called GIPSY for data reduction. My real jobs needed
about 12 hours to run, and I had to start them early in the evening, else
I would have been killed the next morning after morning coffee (when the big
bunch of users -- the ones not being Diploma students -- started to use the
system).
"Back in the old days, we had just 0 and 1, and the 0 were scarce, so we had
a recycling bin below the card puncher and 2 students who would glue the
paper snippets back into used punched cards."
