The primary reason that systems like the 11/730 were desupported
was that DEC didn't sell and support a disk for them large enough
to fit VMS on (VMS itself is small, but DEC's disks for those systems
were tiny).
Folks with third party disks did find that later than supported
versions of VMS would load and run on those systems. After the
disk drives got too small the maximum supported RAM got to be
too small, and I can't imagine changing that since most of those
systems were limitted by bus address space.
Later systems that could boot over ethernet into a LAVC are even
easier to keep running.
None of which has anything to do with the original point, but can
you imagine being a manager at HP and having to explain that you
have to keep an MV 2000 and a VAX 9000 running for compatability
tests? They don't, and I'm sure the affected manager is glad they
don't.
