I had one of these drive years ago. As mentioned in other replies I
want to verify it is a MFM drive and it it does require +5vdc and
+12vdc. I think it is it a non standard interface between the
interface card and controller similar to SCSI but not quite and not
quite SASI either. The original drives were Dos 3.3 but maybe Prodos
drivers could be written. Do you have the S/W that came with it?
