Originally that blocked the Ti-92, but then the Ti-89 and Nspire line had numeric keypads + CAS

Ah yes, I had a 89 Titanium (bought with the funds from a math prize) that felt like sanctioned cheating for College Board exams. The year I took the AP physics test, there was a surreally difficult integral or differential equation that I owed completely to the calculator. I never did as well in math competitions since getting that thing, but no regrets.
