So many whipper-snappers here talking about their TI-83+ and later models. When I was in high school ca. 1994 my trusty TI-82 kept me quite busy writing BASIC games. We used to share games with the data sharing cable, I wonder if any of mine still survive somewhere. I still have the physical calculator tucked away in some box, but it is certain that the batteries are long since dead, and all of the volatile memory faded away.

In high school, my calculus teacher discovered that I had written programs on my TI-82 to help me solve homework questions. Much to my surprise, he approved! He explained that his objective was to teach us to solve the problems using whatever tools we had at our disposal—writing a BASIC program to solve the problem was not cheating, rather it was making the best of my resources.
