Turning Your TI Calculator Into A Hand-Held Game Console

Ever heard of TI-BASIC? It's the unofficial name of the programming language built into your TI calculator, allowing you to program formulae, repetitive tasks, and games into your personal number-crunching machine. Granted, it won't turn your TI-89 into a PSP, but you can get it to generate rolling dice, convert currencies or temperatures, or set up a game of tic tac toe and twenty-one for you and a friend - and yes, you can even set it up to play Tetris.

And really, Tetris is all you need to kill time riding the bus to class, back to the dorm, or during a particularly drawn out lecture on number theory, right? Here are a few handy links to help you start programming your TI Calculator with the games and applications you want:
