About this item

  • If screen dark please lower brightness: Push the "2nd" key on the TI-85. Push and hold the down triangle key on the directional keypad to decrease the contrast. Release the down triangle key when you have lightened the screen enough. The longer you hold down the key, the less contrast the screen will have.


The TI-85 is significantly more powerful than the TI-81, as it is designed as a calculator primarily for use in engineering and calculus courses. Texas Instruments includes a version of BASIC on the device to allow programming. Each calculator comes with a cable to connect calculators (simply a three-conductor cable with 2.5 mm phone connectors on each end). Another cable known as the TI-Graph Link is also sold, along with appropriate software, to connect the calculator to a personal computer. These cables make it possible to save programs and make backups.
