There are plenty of good VAX and VMS manuals out there, including the
documentation set. Check eBay and abebooks.com.
The last version of VMS that will run on a VAX is v7.3.

More precisely, V7.3 will run on *any* VAX, including the primal
VAX-11/780. This level of backwards compatibility is unique.
No, it is not. Talk to IBM about S/360... :-)
Nor is it unique at DEC. Consider RT-11. And possibly RSX-11/M (I don't know
that one well enough -- does it run on an 11/20?)
Yes, unmapped RSX-11M would run on an 11/20. So you could claim that
RSX-11M is runnable on almost any PDP-11 ever made. Of course, you would
not be able to do program development on all of those platforms, but you
could deploy an application.
But RSX-11M in some ways feels and behaves rather different if you have
an MMU or not. So it would not give the same uniform feeling like VMS or
RT-11 would.
