psos is a form of unix, like vxworks, that is intended for embedded
applications (so it isn't surprising that you find it inside there). It
has not near the popularity of vxworks, but operates in much the same
way. When I last used it, several years ago, I preferred the
programmer's interface to the one in vxworks. At that time, it didn't
run on all the chips that we were interested in, but did download to (at
least) the motorola powerpc, and the pentiums that were current in 1995.
I don't believe that it would have changed too much in the intervening
time.

I'll see if I still have any information as to its contents and makeup.
At a minimum, you can be sure that it is still running the modified
version of unix that both it and vxworks run on.
