"Hacking" a scientific calculator

[Elina]

Hi!

Today I got a new scientific calculator since my old one was in bad shape (but still fully functional). And for a while I've been wanting to "hack" it in a sense. The model I'm destroying is a CASIO fx-85GT plus.

I am not very confident with electronics and embedded systems and only know the basic stuff from school classes.
I was wondering if it would be possible to sort-of reprogram the calculator to run slightly differently. YouTube didn't provide much insight.

Probably need some fancy equipment, which I don't have.

Probably not the best place to ask this, but any ideas on how I would go about this?

Most likely would be really hard to reprogram the system. It would be my best guess that you'd need to make your own PCB w/ all the "micro-controllers" in a sense, and somehow convert that to a Serial Port, somehow write (or find) a driver online to communicate with the chips, and somehow decompile the source, and re upload it.

Thanks for the reply, whilst I am not exactly sure what you are saying, I will look into it. I recently purchased a book of "Electrics for dummies" as it was apparently good.
Thanks again.
