2 weeks ago, we revealed you the existence of what was then the oldest TI-Nspire prototype: the TI-Phoenix 1 P1-EVT1 from january 2006.




The previous sentence is not exact anymore, as we've discovered an even older prototype, one of the greatest discoveries in my life if not the greatest.



Did you know that before the handhelds are available, TI engineers are working on development boards?
We had allready revealed you a Nspire ClickPad developement board from october-december 2006 in a previous news:


This development board was coming after the TI-Nspire CAS+ handhelds (september 2006) and before the TI-Nspire ClickPad handhelds prototypes (february 2007).



So today, thanks to Adriweb, we have photos from the TI-Phoenix 1 development board!!!


And of course, it comes before the TI-Phoenix 1 handheld. There are 2005 datestamps on the board!
So you've just under your eyes the new oldest TI-Nspire prototype in the world!



An empty Nspire case with a CAS+ keypad is attached to the board:

Hit any key to stop autoboot:  0

Is it possible to press a key before this counts down to 0, and get into the U-Boot Monitor shell? It has a command md addr len to display memory contents. There also may be a command nand read addr ofs size to read NAND flash into memory (also nand read.oob addr off size to read the extra "out-of-band" 16 bytes per page)

Edit: Unfortunately TI probably set the delay to 0 seconds, which would make it impossible unless CONFIG_ZERO_BOOTDELAY_CHECK is defined (and it isn't in the default include/configs/omap5912osk.h)

I can see the countdown but it's very fast.
I tried to press a key but it didn't trigger anything. I'll try again... Thanks.

We would first have to dump it in order to be able to analyse it...

Nothing has ever been dumped on a CAS+ for now.

does the simular panels for other calculators also contian a calculator witouth keyboard?

No.

It's only Nspire devices which have to be Nspire calculators

No we won't be able to, as Nspire Boot2 are incompatible with CAS+ Boot2.



Anyway, Datamath has finally released the TI-Phoenix 1 page with its test:
http://www.datamath.org/Graphing/Phoenix.htm

The page does include some information I sent after performing my own tests.

Have a look at the OS about dialog box:


Yes, no mention of the "Nspire" name. It's a Phoenix OS !!!

Discover more secrets and higher resolution photos of the OS for now in my news:

If you have a TI-Nspire TouchPad and think that TI batteries are too expensive or too rare in your current location, then this news is for you!

The TI rechargeable batteries have the following specifications:
- 3.7V
- 1280mAh (white battery) or 1060mAh (black CX battery)


NeoCrisis has managed to power his TI-Nspire TouchPad with his Nintendo DS rechargeable battery!
3.7V and 1000mAh

I've taken you a photo of the TI-Phoenix 1 PCB!

If only TI would release the CAS+ OS, in order to to at least unbrick the CAS+ whose OS was removed by error/accident (by trying to upgrade through Menu+Enter+P for exemple...).

As the CAS+ OS is more than 4 years old and totally incompatible with the TI-Nspire, I cannot understand why... It's not like the CAS+ OS file will encrypt more critical informations than the latest Nspire CX OS...
