TI-H: macro units for ti calcs... (ON TOPIC!!!)




would it be possible to design a unit, maybe using PICs or other 
memory/controller devices that could, when plugged into a calculator link port 
would perform certain tasks, like resetting the memory or initiating the self 
test... I have seen a memory clear using two calculators and a link cable, and 
i was wondering if this would be possible with a small unit that could be 
connected into the calculator, and a button pressed to reset the calc (or 
whatever it was made to do.) It would be a good idea for teachers to have 
these because ive seen too many people sneaking answers to exams in, when i 
have reset my calc :(

If anyone knows how this would be possible or has an idea on how to make 
one...
