Alrighty, I know the TI-89 keeps up with date and time. It seems logical that it would somewhere inside the chips and silicon it makes a log of the date that data was inputted...rightttt. I made an idiot out of myself and didn't double check my scan-tron after an exam, my professor jokingly said that if I could prove I actually made an honest mistake and wasn't just trying to magically fix my grade and avoid the ramifications of not studying. So I'm trying to hold him to it and if this calculator saves that kind of info I can show him that my work was correct during the test, but that I'm just and idiot when it comes to bubbling in a little circle.
