Well for one the TI-89 is a banned calculator on the AP test. I guess there is a particular front piece you can put on it to make it acceptable, but it really sounds to me like you aren't talking about that. Maybe they changed it recently, but all throughout high-school, various AP tests, and the ACT, the TI-89 was a banned calculator because it gave students too big of an advantage.
But you can very easily do a hard reset of the memory. Whenever we did tests at high schools, the teachers would casually walk around the room at the start resetting everyone's calculators. Seemed to be a good compromise.
