Read Data input from the floppy disk drive ( FDD) containing clock and data bits. Perhaps the 3 1/ 2 Floppys could even be formatted attached in a way that a 5 1/ 2 controller accepts them? Does someone here have a datasheet of 8272A IC, used in Floppy Drives? Here' s an extract datasheet from the Rockwell R6765 datasheet ( the NEC uPD765 datasheet says basically the same thing IIRC) : RDD: Read Data. I' ve read that uPD765 is compatible but am unsure.
