I ask this because my sister has to get a new, low leveled calculator for some math class she's taking; she can't use here 83+ 'cause it can graph! So what if there was a way to limit its functionality for a test?
Couldn't you just block every key except the numbers and the basic operators? Then it would be impossible to graph/use a program/use Solver etc.
Such a program would probably have to be in ASM and have some sort of password protected way of turning the block off... Could anyone do this?
Also, this is almost certainly in the wrong topic;
I thought about putting it in the ASM or the Project Ideas topic but I wasn't sure...
