Ah. And there is no way to change the mode the ASIC is operating in, I take it? Too bad...

I don't know... maybe...

The ASIC has exactly the same reference as the basic TI-83+ ASIC (TI-REF738X).


I don't know how TI makes it operate in 83 mode or 83+ mode.

Hey! Thanks a lot for nice response :) is it possible to take current ROM on this calc and translate that into English?
Also, where do you find all those ASIC info? Datamath, ti-calc? I'd like to investigate it a bit...

You don't need to translate: you can take a TI-83 ROM, which is the same thing as the TI-82Stats.fr ROM but in english.

And the problem is that we have allmost no info on the TI-REF 738X ASIC, and I don't know where we could get more...

And how do I flash it? Using TI-83+ flashing tools? (Assuming that's so easy.)

Up to now, there is no known software way of reflashing a TI-82Stats.fr or TI-76.fr.

OK, and I doubt someone has a spare 83+ ASIC? I have access to soldering tools so I could experiment...

Actually, I don't need 83+ functionality so much, all I would like is a normal English OS, but full 83+ would be cool too :D
Direct access to flash chip (avoiding ASIC and hooking it to PC directly) is impossible too? I see you found out the pinouts for Spansion flash we have inside...

Update: I'll get TI-83+ soon, so if you need it for some PCB connections check, any photos, etc., let me know ;)
