With the help of a program called TItunes & standard earbuds (and adapter) we can listen to music played by a TI84! Mod you calculator to play music. This only works on a TI84, not a TI83.
This program probably doesn't work for the TI83 because of timer instructions.
But the timer can be easily removed from script and the TI83
also has an IO port, so if you do some heavy lifting you can work it out. THis is a super cool TI calulator hack. It may or may not only play midi.
