    Just as the TI-83 succeeded the TI-82, the TI-86 followed up on the TI-85's advanced functionality while adding a stylish new case, assembly support similar to that of the TI-83, and greater memory capacity, while still maintaining compatibility with TI-85 programs.

    OFFICIAL UPGRADES

    » 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 Connect will only work on MacĀ® computers.

    » 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.

    UNDOCUMENTED FEATURES

    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-86 using the following key sequence and reading the number on your screen:

    [2nd] [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:

    • 1.2
    • 1.3
    • 1.4
    • 1.5
    • 1.6

    UNOFFICIAL UPGRADES

    » 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-86 Turbo Page
    These modifications to your TI-86 can overclock the calculator to 3-4 times its original speed.

    BASIC PROGRAMMING

    BASIC programming on the TI-86 is nearly identical to that of the TI-85.
