The driver to allow IBM AT's (with 1.2 meg floppy drive) to read
and write RX50 disks is RX50.ARC, and it's available on the Spring
1988 VAX SIG tapes, 4th reel (in DECUS library as the RSX/PC/VAX collection)
along with many other useful Rainbow items submitted by the DECUS PC
SIG.
  Note however: I tried reading some disks produced this way on a
VAXmate at DECUS a couple times ago and the VAXmate totally failed
to handle them. A real Rainbow had NO trouble, but it seems the
VAXmate tries to look for a boot block. The RX50INIT program
which is also included with RX50.ARC does not set this up, so the
VAXmate assumes it's dealing with an IBM 1.2 megger. There seems (or
seemed) to be NO way to tell the VAXmate software of this screwup. The
DEC guys on the floor tried repeatedly to get the VAXmate to accept
these RX50s and finally had to give up.
  It is possible this has changed (as, I suppose, it is possible that
there exists a planet named Krypton 8-)  ) but not having access to
any VAXmates around here, I can't say. There are apparently various
BBSs, not all of them Rainbow specific, that have rx50.arc on them.
Good luck...
