The 310 has no "monitor and keyboard" - you just hook a dumb terminal (or
equivalent) up to the console port.
You'll need an OS for it if you don't have one already. When I was using
these things, the choices were Xenix and iRMX. (iRMX is a proprietary OS
that was mostly aimed at real-time, embedded applications)
I *might* have a copy of Xenix for the 310 around, but I'll need to get to
my ancestral home (about 300 miles from where I am right now....) in order
to dig around for that. Remind me - I might not be able to get to it for
a month or so. This would be about 15 years old, and I do not guarantee
that the disks are still readable.
Sorry I don't have more info for you at hand - I think I've flushed most
of what I knew about these machines out of my head ...
