I'm looking for a replacement drive controller chip. Drive reads but
doesn't write and I've traced it back to the 6801 controller chip in the
drive. Anyone have one of these anywhere?
Were there not upgrade chips available that allowed these drives to be
upgraded to a 3.5" floppy drives at one time?
