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
