Well, I do have a fairly old FDC combo (ISA) card here with a FDC chip
marked "WD33C65BJM", and 16000 and 9600 Hz crystals, which according some
docs I found might be good enough (its "33C65 based"). But I can't make it
work with single-density 3.5" disks still :( Is there anything special I
should know (are 3.5" disks different somehow to 5.25" ones for example?)
