I have two TI-83s and a TI-86.
Or maybe it's an 84 instead of an 83? I don't remember.
TI-86 is the best fucking calculator ever made.
83, 84, SAME DAMN THING. Just the 84 had a bit more memory for more games, that's all.Well, the 89s were awesome, but way too expensive.
Never really used a TI-86, so I can't say.
But TI-89s are fucking awesome. They're only like 20-50 bucks more expensive than the current 84s (depending on where you get them). I have a TI-89 Ti, but yeah, biased.
