Have you looked at the new explorer app at all? It is much more capable and better then the old one by far in nearly every way... About the only thing you dont have is the "pi/2" notation. Other then that, it is more interactive, handles more forms of trigonometrics, and is actually useful for learning and doing quite a few things.

It does more advanced translations, simplifications, handles forms, etc. What are you wanting still?

Note, it you really do still want the old one, someone can post a copy of it for you to load. It will still function. Seriously though, the new one is quite a bit nicer.


The nspire OS is a desktop application packaged into a calculator. It is not a good "calculator" and there is a reason the sales on it have been declining since the 2nd/3rd year when they peaked. I think the best review I ever saw was someone on amazon who said "It does a whole ton, but I would never want to take a complicated timed test with it because everything just takes so damn long to do!"
