me too,
you havent lived unitl you've heard this!!!

Wanna know how it worked?

The commodore drives were designed SOO cheapily they had no home sensor,
So when you switched the drive on, it would pull the head back one track 40
times (40 tracks on a disk),
even if the head was on track 1, so you would hear 39 knocks...

You could change the speed (hence pitch) by forceing the head forward the
correct number of tracks then back again,
It was crude but I got mine to play twinkle twinkle little star!

Amazingly the drives seemed to still work!
