The rx50 format is 10 512byte sectors/track, 80 tracks, single sided (stupid)
96 tracks/inch.  The sector header structure is otherwise IBM compatible.
If you hang a 96 tpi floppy on an IBM clone you can write that format by
calling the ROM bios with a nonstandard disk setup.  I have a program that does
that which i can post or mail if there is any demand.
