[Coco] Super Disk; was: Help floppy drive

[coco at yourdvd.net]

I remember going through all that wonderful stuff on FETS and OP-AMPS
when I attented school - it was actually fun.
I believe the superdisk is an optically (laser) tracked medium - the
120mb disk uses a laser to track the head when in 120mb mode, or so
i've read... -r
