Title: New Ndless+, finally for the TI-Nspire CAS+
Post by: critor on January 23, 2013, 06:51:10 pm

In 2006-2007, Texas Instruments evaluated the TI-Nspire CAS+ in some pilot classes, a prototype whose first known development traces take us back to December 2005 (http://tiplanet.org/forum/viewtopic.php?t=8673) with the TI-Phoenix 1 development board.

(http://tiplanet.org/forum/gallery/image.php?mode=medium&album_id=49&image_id=397) (http://tiplanet.org/forum/gallery/image.php?mode=medium&album_id=49&image_id=1608)

'P1 / Phoenix 1' is the internal code name of the TI-Nspire CAS +, while the production TI-Nspire CAS ClickPad we know have the internal code 'P1R2 / Phoenix 1 Release 2'.

The latest TI-Nspire CAS + produced to our knowledge were manufactured in October 2006. After that, we have a time gap before the first TI-Nspire ClickPad prototypes from February 2007. During this gap many things have changed, including the processor which did migrate from the OMAP Technology to ASIC technology, the OS interface and the keypad.


Texas Instruments has never provided any support for prototype TI-Nspire CAS after the launch of the TI-Nspire in April 2007. So, users have remained for years without the possibility of updating their handheld or simply repairing it after removing the OS or the Boot2.

Fortunately, most of the TI-Planet team, together with prominent members of the international TI community have worked very hard to develop tools for dumping as many different versions of the OS, boot1 and boot2 as possible, and have rebuilt at last (https://tiplanet.org/forum/viewtopic.php?f=43&t=9227) installable OS files for those handhelds! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

(http://tiplanet.org/forum/gallery/image.php?mode=medium&album_id=49&image_id=804)

All this would never have been possible without the discoveries from Adriweb, Jimbauwens and myself for the TI-Planet team, and Bsl and Goplat for the international TI community, showing again that together we are strong! ;)

In this context, we would like to thank all those who have given or loaned TI-Nspire CAS+ prototypes to us, but also those who 'dumped' some versions for us: the Datamath museum (http://www.datamath.org) and some Omnimaga (http://www.omnimaga.org) and cnCalc (http://cncalc.org) members.



After all this work in a previous news (http://tiplanet.org/forum/viewtopic.php?t=10974), Goplat finally offered you a version of his Nspire emulator supporting the TI-Nspire CAS +! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

(http://i43.servimg.com/u/f43/13/23/13/53/cas33410.png)

And thanks to this emulator, Bsl grants you tonight with a new Ndless version, Ndless+ which brings assembly to TI-Nspire CAS+ running OS 1.0.529 and 1.0.554! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

Now, the TI-Nspire CAS + can therefore, after a simple recompile most often, benefit from all allready released Ndless tools and games! ;D(http://www.omnimaga.org/Themes/default/images/gpbp_arrow_up.gif)

As always, awesome news!
But aren't the CAS+ ones rather rare anyways? :P

Somewhat less so than some Clickpad prototypes, but immensely rarer than production models, obviously. We're talking about an estimated several hundreds of models in (potentially) working state at this point...

Why do programs require a recompile? Does this Ndless version not implement the SWI-based system calls?

It certainly does, but by now, Ndless 1.0/1.1 is just as thoroughly outdated as CAS+ Nspires are :)
Many second-generation (1.7/2.0) and third-generation (3.1) Ndless programs won't work, even after a recompile.

Very nice work once again guys!

Well done once again guys. Continue the good work.

I wonder what TI thinks of this.
Anyway, great work! Nice to see these kinds of developments

I've been waiting for this for a rather long time, but it was worth it!!

Thanks to all developers!!!  :thumbsup: :thumbsup:

Isn't this the calculator that was so prevalent a few years ago on ebay, because sellers were getting rid of their prototypes that they got for free?

Now I want one.....

The CAS+ sucks, seriously.

Isn't that mainly because of the software limitations, though? I was under the impression that the CAS+ had really similar hardware.

Title: Re: New Ndless+, finally for the TI-Nspire CAS+

The CAS+ has OMAP-based hardware, while the Clickpad have Zevio-based hardware: different microcontrollers, MMIOs and devices, AFAIK.

Well, that's interesting. I've never heard anything evil about OMAP, though.
