The DD part sounds rather like what Altos used on their 8" DD disks,
and which no PC FDC that I know of can read. I doubt that they did
the SD header part though. Have to fire up my Sierra (Altos clone)
and see if it can read the RX02 stuff - or at least look at it with DU.
Soooo, it is caused byt the RX02! FYI the RX02 can
read RX01
but RX01 cannot read RX02 unless the RX02 formatted the media
as RX01. RX02 is DUAL density whereas the RX01 is single.
Gotcha!
