Identification and Background ¶ 

The TI-92 is a 3D-capable graphing calculator made by Texas Instruments. It runs on 68k of RAM and on a 10 MHz Motorola 6800 processor. It has a 240×128 pixel black and white display as well as a QWERTY keyboard. The TI-92 is considered a computer because of this keyboard so its use in standardized testing is not allowed.

Through a loophole, programmers can use the Assembly programming language to modify and create programs on the TI-92 giving the calculator great versatility.

The TI-92 can be identified by the label TI-92 on the upper right hand corner of the screen.
