Intel sells a box bundled with RMX II called the 120. It is their 301Z
system (386, 0 wait, 16 MHz). The software allows you to create two
partitions on a hard drive in the box, one with DOS and the other with
RMX. There are utilities that copy between both (from DOS to RMX under
DOS and RMX to DOS under RMX) and allow you to boot the system under
the other OS from the currently running one (i.e., BOOTRMS from DOS and
BOOTDOS from RMS). You can develop under either environment and port
to RMS for the final product. The last time I touched the system,
the disk drivers worked with the standard WD MFM controller and about
6 hard drives up to 140 megs. The system required that you have a
360K floppy as the boot floppy for RMX. The console talked to register-
compatible EGA cards, and could talk to the parallel and the two
com ports (1 and 2). I think a full blown system with all tools, 4 megs
of memory, and an 80 Meg hard drive was around $12,000. That was for
development. The end system priced dropped quite a bit.

One note: Intel added an EPROM at segment $E000 that looked first in
the CMOS ram to see which was the active partition and then booted
RMX if it was active. I found I could copy this prom, drop it into another
generic 80286 or 80386 box, and bring up RMX. That may have changed
too. I never carried it very far because I found no real reason to
pirate RMX 8).
