Limiting calc abilities?
« on: October 30, 2012, 11:03:41 pm »
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...

They still wouldn't accept it, unless your teacher was a member of this forum and trusted her and you.
You can just buy a four function for a buck or a scientific for 10.

Sadly the 83+ is easily hackable, so it would be hard for teachers to trust any APP that can block programs, unless there was some sort of APP validator when linking your calc to the teacher calc so the teacher can compare his version with yours and ensure that the entire code is exactly the same.
