    The TI-83 was released as the successor to the TI-82 and featured a newer, more contoured case design that has since been used on all of TI's newer calculators. The TI-83 features backwards compatibility with TI-82 programs and some newer financial functions, but by far the most notable aspect of this calculator is built-in assembly programming capability supported by TI itself. This advance saved curious programmers the trouble of "hacking" the calculator themselves to achieve this functionality, and marked the beginning of TI's embracement of assembly programming. The TI-83 was a popular programming platform, but has now been replaced by the TI-83 Plus, an updated model.

    » 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-83 using the following key sequence and reading the number on your screen:

    [MODE] [ALPHA] [S]

    WARNING: After entering the above key sequence, DO NOT PRESS ENTER! If you do, your calculator's memory will be erased. Press any other key to exit back harmlessly.

    Known ROM versions:

    • 1.O1O
    • 1.O1OO
    • 1.10001 (TI-82 Stats)
    • 1.02

    » IR Link
    The IR Link allows you to control infrared devices from your calculator or communicate with other calculators (to play games or chat) over a wireless connection.

    » Link Cables
    Link cables let you transfer data files (such as programs) between your calculator and your computer.

    » Power Extension Page
    The Power Extension instructions will show you how to use AA (instead of AAA) batteries without making any modifications to your calculator.

    » TI-83 Turbo Page
    These modifications to your TI-83 can overclock the calculator to 3-4 times its original speed.


    BASIC programming on the TI-83 is nearly identical to that of the TI-82.
