Free, Open Source OS For TI Calculators

nicklaszlo writes "TICalc.org announced yesterday that Patrick Pelisier has released a new beta OS, called PedroM, for the TI-89 and TI-92+ under the General Public License. Here is the source and binary. This is the first time a TI calculator has been free of proprietary software. The OS has 32 commands and backward compatibility for assembly programs. You can get a Windows/PC emulator of both calculators, for those who don't have either calculator, or don't want to risk their real system."

Yeah, it will, but there's already pressure on TI to improve their calculators. This came in the form of HP re-entering the graphing calculator market with several new calculators of their own including one which is far more powerful than any other calculator today. This isn't a concern for TI to make a better product, just because they don't charge for upgrades to the AMS (and aren't necessarily losing money if you switch away), because TI still produces the hardware, and because if you want the powerful math features of the TI-89 you still need to use the official AMS.

You won't believe this

But back in grade 10 high school, a close friend of mine actually wrote a GUI Windows-like interface for the TI-83 calculator. It included start-menu style popup menus, Notepad application, etc. Super-crazy.

These TI's have Z80 processors in them, anyone who knows Z80 assember can pull off some pretty amazing shit.

This would be great except one thing...

If you install it, the calculator no longer does math.

Kinda defeats the purpose of having a calculator, no?

Now if someone ported the yacas engine to it, and made it similar to the original interface, that would be something!

I'm not going to put an alternative OS on my calculator that just plays games, when I can have a gameboy advance for $100 and get color too!
