Funny. When I started Georgia Tech in 1977, they still used slide rules but they quickly started to disappear with calculators like the TI-55 or the more expensive HP35.
That said, during one Chemistry class test we were asked on a question to calculate the number of moles in a substance and given two numbers to multiply was all that need be done. I laughed when I realized WHY that question - all the calculators were flashing “E” for error, over capacity.
Professor had included it to demonstrate the power of logarithms (adding two logs is multiplying, etc.). With a slide rule it was a few second process and I got the answer with the slide rule I could only afford at the time. But I very soon there after went digital. Graduated in 1980 - 12 straight quarters for a BSEE from The North Avenue Trade School (as we called it).
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)
