Touch pad navigation is very nice! It does suck that youtube's re-encoding messed up the video a bit though.

Vimeo reencoding (if any) seems to be quite better:

Thank you very much for the news.

Some little precision: TI-Nspire CAS prototypes can come with "special" OSes 1.1 or 1.2.
We just ndlessed the most recent OS, as there is a downgrade protection (all TI-Nspire CAS prototypes can be upgraded to 1.2, but you cannot downgrade back to 1.1)

Did you notice how the TI-Nspire CX screen is much smaller than the TI-Nspire screen?

I couldn't find the screen dimensions on TI website, so I've just calculated them.
The TI-Nspire CX screen is 25% smaller, no bigger than a TI-83+/84+ screen.

Find all dimensions and schematics in the TI-Bank news:

According to some TI staff (T3 teacher from Univers-TI-Nspire who has "worked" on the 3.0 software), the new 3.0 OS will be installable on old TI-Nspire Clickpad/TouchPad, but we'll have to use documents which are "not too big".




As TI had never mentionned a free space problem with the 2.1 OS (although there is a problem: just look at the chart...) I'm very frightened this time...

Feel free to translate some parts and/or reuse some images if you'd like to make a news about this.


Let's try to guess what the remainging free space (with no user documents in memory) will be.
4Mb on the basic TI-Nspire, and 6Mb on the CAS TI-Nspire ? We wouldn't be able to play nDoom any more!
They've finally found out how to prevent students from using Ndless and playing games: after the "no programming", comes the "no memory"!

Is there anythng to change in the Makefile or in the headers?

I cannot recompile code which did compile on the previous r369.

I didn't modify the code, and I've performed a "make clean"...



Edit: It doesn't seem to come from the makefile or from my code...
I cannot even recompile the samples.

Ok guys. I've filmed the 1.1.7xxx diags code yesterday. It took me 90 minutes, with the finger on the down arrow, and exiting/restarting the NAND reader every 5-6 minutes as there is a bug (see above).

That diagnostics version is quite interesting, as it has a NAND reader and a NAND writer too. So you can read and modify anything in NAND, yes anything (like the downgrade protection for example).
It's very important to dump it, as we might be able to flash it on TI-Nspire CAS+ calculators for example and understand more about those older and strange prototypes running the 1.0 OS.

The range is 16B000-20FFFF.

But some some areas are filled with 0xFF bytes:
1CED0B-1FF7FF
200C90-20FFFF

So it seems we only have to dump:
16B000-1CED0A
1FF800-200C8F


Could some of you try to OCR the video with the appropriate tools?

I still have to dump the boot2 (it'll probably take me 3 hours) and the OS (...).
But I'd like to get some comments with the OCR first, before filming again.

Here are the files:

Thank you very much for helping.

So this was one way of making a much smaller TI-84+.
Here's another way with a sliding keypad, but I've spent much less time on it:

Hmm, I doubt TI would make a sliding keypad. The keys that get recessed would be a lot harder to access.

Yes, me too.
Sincerely, the clamshell TI-84 pocket.fr is more probable (and better).

Here's a way.....smaller screen, Nspire Alpha's buttons for everything, li-Ion battery

TI has indicated that the screen size will be the same.

YES,  if that is real, I spy a app/prgm button :O

"apps" and "prgm" buttons are in the top right hand corner... what do you mean?

Just have a closer look:


No specifications yet.
