30 years ago, we had the option of the TI-82 Or (83?) and the 85. A bunch of the kids with the 85 were playing Tetris and some were writing little programs. I got the cheaper 82/83, and I don't actually remember using it for anything, even once, even though I did the IB track (stats, trig, algebra, calculus, etc).

I was in the not-TI-85 club for a while. I think I had the TI-84? You could still write programs but your variable names could only be one letter. When I upgraded to a TI-85 and got Tetris a friend who had the not-TI-85 asked if his could play Tetris. I checked out the Tetris code and saw there were less than 26 variables, so I figured it could be done. I spent several English class periods porting the TI-85 Tetris code to the not-TI-85 and I got it to work. All the not-TI-85 owners loved me, lol!

How is that possible?

I wouldn’t have been able to function without it in school (20 years ago). But we also didn’t have iPhones.

  • Back in the mid-90's we had a TI version of sneakernet where you would copy programs from one student on to your TI-85 via a link cable; this is how I got Tetris back in the day. I assume OP did the same.

    • IIRC there was a way to connect the TI-85 to your serial port and use some Windows or DOS software to copy files onto it. (Everyone's PC still had at least one serial port on it back then).

    • Was it that only the 85 could connect to a com port, but then you could connect the 85 to the 82/83? I seem to remember pleading with the one kid with an 85 (who didn't even care about games).

  • (Edit: I am assuming you were asking how it's possible I didn't use it, not how it's possible that people were copying programs onto their calculators.)

    I don't know. It's been too long. We must have done graphing on paper.

    I don't remember a lot of coursework in math that required me to produce a decimal value. For example, we wanted √2 instead of 1.414.

    In physics, I think we used regular calculators.

    I used to be bewildered at my parents not remembering certain things from high school. But, now I'm living it :).
