I don't remember ever seeing a calculator in college and that was up through 1978.
The office I worked in didn't get a computer until around the mid '80s, IIRC. That was 2 floppy drives, all line code commands, no GUIs, no internet, no Office. Didn't have a mouse. Only 3 or 4 us figured out to use it to any practical effect. ;O)
1980....Our professor said no calculators...and we used the slide rule. Said he wanted us to learn to anticipate what the answer should be +-
Well, then your college was a little behind technology, I guess. I had just completed 8 years in the AF (68-76) and was on a TDY team that optimized communications links all the way from Iceland down through Europe and onto Greece and Turkey.
We were using HP35s for the testing and at the end were given HP45s.
