i am the sort of person that carries a ti calculator around

and actually uses it

@ky0ko that was me with my hp-28s, back in the day.

it had a square wave generator for beeps that you could assign frequency and duration to, so i'd put in arrays notes to listen to my tunes

the older ti ones had a serial port that was audio jack shaped and there were programs to play compressed audio files using delta modulation

unfortunately the ti-84 plus ce got rid of that in favor of a usb port and to my knowledge nobody has written a usb audio driver for it yet

it might be possible, though

@thomasfuchs i like the ti graphing calculators. i have a ti-83 plus se and a ti-84 plus ce, and my first one was a ti-85

@thomasfuchs ok and now thanks to girlfriend i also have a ti-84+ and a ti-89

i also remembered i have an nspire at my parents house

@ky0ko if you ever stumble upon it, the early HPs are fascinating, e.g. the HP-67
