Remember I wanted to upgrade the cheap TI-82Stats/76.fr (= TI-83) with a great TI-83+ OS ?

I couldn't do it up to now, but...


I have managed a similar upgrade with Casio!
Just upgrade your cheap Graph 35+USB / fx-9750Gii (= TI-83) with a great Graph 85/75 / fx-9860G/Gii OS (=TI-84+SE).

In fact, the Graph 35+USB / fx-9750Gii have a 4Mb Flash ROM.
But the installed OS doesn't provide any archive memory, and doesn't accept applications.
And officially, there is no official software to flash an OS on that model.

After flashing the model with one of the OSes mentionned above, you get:
* archive memory support! (1.5Mb)
* application support!

The hack is simple (long but simple).
No hardware modification -> no special tools needed -> free updrade.


Could some french-speaking people check and try to upgrade their Graph 35+USB / fx-9750Gii ?

I'll post a news once the tutorial will have been tested.

Thanks.


Let's all migrate to Casio! Much more upgradable calculators!


(if you have a cheap scientific fx-82ES / fx-83ES / fx-85ES / fx-92 Collège 2D calculator, you may also try this tutorial in order to upgrade it with a simple pencil -> http://casio.bank.free.fr/index.php?mod=archives&ac=voir&id=93 )

Cool, that's what I have.
If this is done, I might start actually using my 9750gii 9860gii...

I don't see any toturial, just "You can do this, it does that"...?

I have FA-124, but I never really familiarized myself with it.  How would I send the OS?

Click telecharger, the tutorial in there explains how to change your calc to another. Unless your computer can't view the file properly?

Hmm good question, as I haven't used a Casio in ages. X.x Did you check online doc and stuff? Maybe Casiocalc.org?

Also why don't you bump the topic instead of editing when it has been more than 6 hours? Nobody will notice if the post is at the very bottom of the list.

Cool to hear! Post pic?

Nice. I don't remember what OS version I have on my 9860G. I know it's 2.0, though, because it adds string support.

Btw there's an add-on for the 9860G that allows you to speed up the calc. I don't know if it's slowed back down if you run another add-on, though. I think it's on Casiocalc.org file archives somewhere.

Parts of it were kind of hard to understand.
And the tutorials on casiokingdom were a life saver

Hi. I'd like to write an add-in for classpad 330 in c++. Do you know somone who can help me? Thanks,
