Get a AM radio and have fun with music from your PDP-8.

It's a video of a floppy disk drive playing music by screwing with the
stepper motor. It is my understanding that the video was a hardware
hack, but it got me thinking... For those who know floppy drives well,
do you think such a thing could be possible via IBM PC floppy controller
software calls only? Or is a hardware hack required to generate the
right frequencies?
. . . but think what you could do with the stepper of an SA400
(or SA390 (Apple))
Run it backwards and it will talk about billg
