However, one thing I have to mention about the fx-ES calcs (not the fx-ES+ ones) is that they apparently all use the same hardware and all you need to do to switch the model number and functionalities is using a graphite pencil to fill the little dot things (I think they're called jumpers) on the calc motherboard. Graphite pencil lead is an electricity conductor, so basically you don't even need to do any soldering.

There is even a (French) tutorial at TI-Planet https://tiplanet.org/forum/archives_voir.php?id=4241

It's an quite old trick, and the hack can only be done on old VerA models, which are quite rare now. (CASIO knew that bug, so the company once set up an exchange program. Most of the people didn't know the fact so they just went to send their VerA and got an all-new VerB.)

However, several hack can also be done on a VerB model. There is a video named "Hack your fx-82es VerB" on YouTube (It's uploaded by me!) telling you how to use a bug to upgrade  an fx-82es to an fx-991es.

DJ Omnimaga:
Interesting, I didn't know about that program by Casio. Also thanks for the head up about the video. :)

Adriweb:
is the video .
And that was amazing, how did you find that lol :P

Tjakka5:
That is amazing, I didnt even knew calculators were able to do that!

Hmm in the first video of the series he says the bluetooth module communicates over UART and the calculator apparently has UART in it (rx tx lines) Perhaps you can program it over uart?
