I've spent much time using RMX and VersaDos, both real-time OS's.  What
I want to know is why ya'll hacked up Unix.  Why not just get RMX on an
SBC, connect via ethernet to a UNIX system, and run with that?  Cost
is one concern no doubt.  Plus the academic thrill of hacking UNIX.

I've always thought marrying two systems, each of which is excellent
(no flames, please) at what it does, would work nicely.  Is anyone *out
there* doing this type of thing?
