I’m kind of obsessive about checking my analytics report to see what people are searching for. Lately, I’ve noticed the search coming from time to time “how to upgrade ti-nspire to ti-nspire cas.” This one makes me chuckle a bit (sorry if you arrived here on that search phrase and I’m chuckling at your expense).
I would never put anything past the resourceful hackers/programmers at sites like ticalc.org an Ominmaga. That said, I have to believe Texas Instrument has done everything to make it somewhere between impractical and impossible to transfer the TI-Nspire CAS OS onto the TI-Nspire (non-CAS). If it was feasible and practice became widespread, it would force the people of ACT, and other tests that ban CAS calculators, to reconsider whether the TI-Nspire should be allowed on their exams.
So, unfortunately, there’s no way to put the TI-Nspire CAS operating system onto the TI-Nspire. It’s not a total loss. If you purchased a TI-Nspire and realized what you actually need is the CAS version, you’re best option is to sell the TI-Nspire and buy a new TI-Nspire CAS. As I mentioned on another recent post, it’s really easy to sell graphing calculators on Cash-4-Calcs. If you used up a chunk of change on the Nspire and need to get a good deal on the Nspire CAS, you can find one really cheap on Ebay.
