Free, Open Source OS For TI Calculators

Posted by timothy on from the smallness dept.

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."

    I agree, what is the point? A TI-89 goes for around $140. You can get a good handheld for like $200-$300 that does all of the things that TI users dream of by default. You are trying to put a square peg through a round hole with a doughnut. Wrong toll for the wrong problem. If you are going to do math, get a calculator, if you are going to do computing functions get a handheld.

    TI calculators would be a lot more interesting if they didn't force me to use algebraic entry. A modified OS that let me turn "=" into "enter" would be a big step forward.

    In the meantime, I'll stick with my HP-41CX and HP-16C.
