The -85 was released in 1992, iirc it's TI's second graphing calculator. The -83 is a later model.

They did! The TI-89 is how I aced the AP Math exam.
The TI-92 had recently come out, and it had a QWERTY keyboard and could solve symbolic calculus problems like "find the derivative of 2x^3". This was a problem for the AP exam, since you could just type in the problem and get the answer. They fixed this by banning calculators with QWERTY keyboards. That's just about exactly when the TI-89 came out, which also did symbolic calculus but did not have a QWERTY keyboard, and so it was totally allowed on the exam. Boom, 5/5 exam score for Jorji.
