Back when there was a Prisma, we check-out lots of stuff for the service
processor in the machine and VxWorks won by a landslide.  Familiar
programming interfaces, good network support, great cross-machine support
with across-the-network debugging from a Sun workstation, etc, etc, etc.
VxWorks just comes across as something built by people who wanted to
get something done in a systems sense, not just build a little kernel
for multiprogramming.  The VxWorks/Heurikon 68030 development crates we
bought from Heurikon worked as advertised and all the software did likewise.

We did NOT buy the 80K source license, but got some of the stuff for
retargetting, etc.  We actually didn't WANT to hack the source - 
a real requirement was that we didn't want to own the base software in
the service processor and not having source encourages that.  Seemed
like a fine decision even in retrospect.

So, good hunting - hope your project works!!!
