Oh, one thing to remember... RX01's use single-density (FM) encoding,
and RX02's use a mixed-density (FM for sector headers + MFM for data)
encoding. You won't be able to read RX02's for sure (and probably also
RX01s due to their header format) on a PC's floppy disk controller.
Somethink like a CatWeasel or other similar controller probably could do
the trick, or you could build your own disk controller. :)
