(bit about Unibus controller trying to emulate a Massbus one omitted)

I think Henry has it right.  I would add that sometimes you can lean on
the foreign peripheral vendor (of the system interface module in most
cases) to provide patches to make their product work on your system, if
they advertised it as working there.  E.g. "Works under RSTS/E, RSX-11M,
and UNIX".
