 The D Bit [[http://www.dbit.com/fddc.html|FDDC]] "is a DC-DC converter which boosts/negates the voltages from a PC power supply to those needed by most 8" floppy drives. It can attach to an IDE power connector on a PC's power supply that has sufficient capacity to power both the PC and an 8" drive". The D Bit [[http://www.dbit.com/fddc.html|FDDC]] "is a DC-DC converter which boosts/negates the voltages from a PC power supply to those needed by most 8" floppy drives.

-Care must be taken to ensure the +5V supply to the drive is well regulated - otherwise, damage to the Applesauce may occur.+Care must be taken to ensure the +5V supply to the drive is well regulated - otherwise, damage to the Applesauce may occur. In addition, remember to always power up the Applesauce before powering up the floppy drive. And power down the drive before powering down the Applesauce. This will help to reduce the chance of potentially damaging the AS by having power back fed into it.
