Has anyone managed to enable CAS functionality in the regular TI-Nspire?
« on: April 19, 2012, 05:19:53 am »
Hey all. I've been searching around off and on for a while now trying to figure out if anyone has managed to enable/install the functionality (in part or in whole) of the Computer Algebra System on a regular TI-Nspire.

My model isn't the latest one but the original (I think) TI-Nspire Touchpad.

I'm not looking for the ability to play games and I'm not looking for some crazy OS overhaul. I just want to know if anyone has managed to make the infinity and +/- functions not useless.

Thanks in advance,

GA

The answer is "yes", with a number of caveats.
The topic comes up fairly often, so for more information, you may want to search the forum (e.g. the news section) :)

Hi everyone.

My question is the same. A friend of mine bought the non CAS model by mistake and really neeeded the CAS functionality. I have looked on the internet for a while and couldnt find anything to install to enable the CAS (or some functions at least) or load the CAS OS into a non CAS TI-Nspire.

I also have searched around the News section here in the forum, and didnt find anything, just some threads saying "yeah, its possible, somehow".

Could anyone point me some direct link about it?

Sorry for the bad english and thanks for your patience :)

"somehow" is called OSLauncher, whose core functionality is merely five C statements, and the Clickpad/Touchpad version can be downloaded from TI-Planet :)
The beta version for CX calculators can be downloaded from http://ourl.ca/15463 (explained in French at http://tiplanet.org/forum/viewtopic.php?f=43&t=8879 ).

For the (original) purpose of launching DummyOS, OSLauncher works very reliably :)
For the purpose of launching the CAS OS on the non-CAS calculator (and vice-versa), OSLauncher is very unreliable on most calculators (read: you'll often have to execute OSLauncher dozens of times), and before it has the slightest chance to work, you need to somehow obtain the decrypted version of the OS, which can require understanding, modifying and building C source code and executing the resulting binaries.
