I used a TI-83 in Calc class. Had a great instructor - he WANTED us to use the calculator to make sure we got the right answer, but we had to show HOW we got the answer on the test. I don’t think any of his tests had more than 10 questions, you could fill half the page showing your work for a single question.
sounds like it. I know the Ti-84 had better calc graphs but it worked well enough for me..
I honestly can’t remember the tests. I think we worked out the problems and could use our calculators. The late 70’s it was all on paper.
