Yes, thats it, 5 1/4" floppy band positioner steppers. 3 1/2" floppy steppers are too wimpy... The 5 1/2" steppers probably also have higher output voltage since they originally ran on 12V vs 5V for the 3 1/2" floppy drives. > > -- > Cheers, Gene > "There are four boxes to be used in defense of liberty: > soap, ballot, jury, and ammo.
