No VMS support that I know of.  The DX11 was a rather uncommon beast.
I believe it was a 6 foot rack full of little M series modules (and
perhaps even older modules).  Built by the CSS group, I believe.  When
I heard of it, it was definitely used with a PDP11 at one end, not a
VAX.  One of my co-workers in the RSTS group used to support that
beast; he had a box or two of IBM-side diagnostics card decks in his
office.  I guess the primary application was as a PDP11 to IBM/360
interconnect, so the PDP11 could act as an IBM front end or something
along those lines.
