<p>i dont think at our school we have to clear our ram..</p>
<p>Still when I clear my RAM on the TI 83 +, it gets rid of all after-market programming, but everything that was there out of the box is still there. my question is if I clear the RAM on the TI 89 T, will only after-market programming be erased or will some of the original stuff go away too. I only ask this cause theres so much stuff to potentially loose.</p>
