As I understand it, the Rainbow MS-DOS format program will NOT produce
RX50's.  You need to use the Rainbow CP/M format utility.  It is supplied
with CP/M V2.10 (I don't know about previous versions).  With this program
you can "make" RX50's from any (soft-sectored) SS-DD diskette.  You can
use DS-DD disks, but the second side will not by used by DEC equipment.
DEC recommends you use disks without hub-rings; though I haven't had any
problems (yet) with hub-rings.
