    The TI-92 Plus was available as both a standalone calculator and a module upgrade to the TI-92. It added additional memory, flash-upgradable ROM, and advanced mathematics software. A TI-92 Plus is functionally almost identical to a TI-89. The Voyage 200 has since replaced the TI-92 Plus, since it offers additional features.

    » TI Connect
    The TI Connect is the latest link cable produced by TI. It has a higher data transfer rate than the TI-Graph Link cable. It's a USB cable and lets you transfer data files (such as programs) between your calculator and your computer.

    » TI-Graph Link
    The TI-Graph Link is the older link cable produced by TI. It does not have as high of data transfer rate, but it does work wih almost all calculators. It connects to your serial port and like TI Connect is widely used to transfer data files (such as programs) between your calculator and your computer.


    From time to time, TI will update the internal code of their calculators to work around bugs, optimize functions, and even add features. This results in several versions of each calculator in the marketplace. You can check the ROM version of your TI-92 Plus using the following key sequence and reading the number on your screen:

    [F1] [A]

    Assembly language programming capability is built-in to the TI-92 Plus. Assembly programs written for the TI-92 must be modified to support the TI-92 Plus.

    For software development, we recommend GCC4TI.
