'FDD Speed question'
1995\12\18@161115 by Damien M.Wiles

I may be a little off topic, but does anyone know how to get a floppy drive
to spin at 750 rpm. I am using old 5.25 drives, the motor seems to have a
comparator and bridge driver, but the adjusment pot makes little difference.
               Any clues would be appreciayted.

Hmm, strange question, wonder why. Assuming the motor can produce
enough torque, there will be an oscillator somewhere setting the
speed, maybe a divided down xtal? Or perhaps RC, if it's not that
critical, trace back to find what drives the driver. If it's a
newer one there may be little help, it may all come off one crystal,
into one big VLSI
