A few years ago, I heard about RMX being avilable to run on PCs. If you know anything about this, let me know how well it works. Just if you are the currious type, here is why I ask .... In my work environment, I need RMX for some systems we develop. DOS is not a real operating system, but we use some of its applications alot (PCAD). As a programmer I would love Unix. Any problem with a large 386 based system, with each of these on different partitions?

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).
