I think P/OS *IS* RSX; the P/OS "Toolkit" merely gives you DCL access to it.

I have Whitesmith's C compiler and DEC's Pascal compiler.  For the
informal programs I wrote, the Pascal produced code that was about
the same size but about 50% faster.  So I only use Pascal...

You can get RT-11 from DEC, Venix from VentureCom, and TSX from
whoever it is that you can get TSX from (oh well).
Of these, I've only used Venix (I run P/OS on mine because I need
the real-time multiprocessing features that RSX offers).  Venix is
passable Unix, and claims to have real-time support in the kernel
(pre-emptable processes, asynch I/O, 1/60 second sleep increments,
etc), though I've never tested these.  Trouble is, it'll run you 
about a grand.

I got my PRO-350 on the cheap, since I'm a professional part-time
grad student at Stevens (I'm getting ready to finish my second
Masters - if I don't start another, I might lose the cheap maintenance
contract!).  Sometimes I'm tempted to upgrade to a 380, or get a
bigger hard disk (I have 10Meg), or get Venix, or all three.  But
then I remember that the PRO series has been abandoned, and that
only weirdos like me get nostalgic about PDP-11s, so I drag my feet
about spending the money.  All the software I got came with the
machine (more or less - it's amazing what gets passed around
college campuses these days).  And when RSX-11 was *CURRENT*
the phrase "public-domain" had not been coined with respect to
computing.  So good luck!  And by all means,
	 LET ME KNOW WHAT YOU FIND!!!!!
