Take a look at the CQD-220/TM or CQD-240/TM at www.cmd.com. I have two
CQD-240/TM that I bought recently (25-Jan-99) from Ficomp (www.ficompinc.com),
that I am using in my uVAX II with Ultrix 3.1. These boards emulate
MSCP and TMSCP. According to the technical manuals on CMDs website,
these boards work in: LSI-11/23, PDP-11/23+, Micro-PDP-11/53, 11/73,
11/83, 11/93, uVAX II, uVAX III, VAX 4000 and DECSystem 5400 systems.
They support RT-11, TSX, DSM-11, ISM-11, RSX, RSTS, VMS, UNIX, ULTRIX,
and other operating systems which use DU/TU drivers.

I am happy enough with the ones I have, I am going to buy a Unibus one
for my 750 when it arrives.
