"This must be the ultimate in retro-cool hardware hacking. The floppy drive is obsolete, but the turntable is not, and that got one guy to thinking. He provides a full tutorial on how to turn that worthless old floppy drive into a most desirable piece of audio gear."
Sadly, the site it links to is overloaded, but they're working on it.
