looking for iRMX O/S for 8086

I'm trying to find diskettes and manuals for a release of iRMX that runs on an Intel 310-3A box (8086 processor). I have 2 of these running production electronics testing that have died. We are getting them repaired by InBUS. But we've never used the backups that were given to us when these machines transferred from another plant. We didn't get the original iRMX diskettes, and just a couple of manuals. I suspect the backups may be for just the application software, and not the entire hard disk (there are only 3 diskettes in the backup set). As far as I can tell, we are using iRMX-86 release 6. I've been trying to get someone at Radisys (who support the current version of iRMX), but haven't been able to speak to anything more than voice mail so far. I'm not very hopeful, though: this is pretty old stuff. Does anyone still have the diskettes and manuals for this release that I could copy or purchase? Thanks, Clark Geisler Test Engineer
