About the calculators

The TI-83 Plus is a portable gaming device developed by Texas Instruments. Released in 1999 as an update to the TI-83, the TI-83 Plus features state-of-the-art gaming hardware, including the following:

  • 96×64 monochrome LCD
  • 24 KB memory, 160 KB storage
  • 6 MHz Zilog Z80 processor

Following suggestions by teachers to add math features to the device in an effort to encourage gaming in class, the number keys, originally meant for number-guessing games, were repurposed for arithmetic. Since then the device has been labeled a "graphing calculator." However, this is a misnomer; the mathematical functions were only added as an afterthought.

It is the only gaming device allowed on the SAT, ACT, and some AP exams.
