Emulex Qbus Disk controller? (Need help identifying this one) - test-drb@ccmp.vtda.org

 From the Field Guide to Qbus and Unibus Modules:

http://world.std.com/~mbg/pdp11-field-guide.txt

It would appear that you have the following:

QD24        Q   Emulex ESDI disk controller.  Emulates MSCP.
                For VAX 3500/3600

I'm not sure which one you really want, but it is probably
in the Field Guide, possibly one of the UC controllers.

I'm trying to bring up NetBSD on a Vax 4000/300, and so I'm
looking for a MSCP SCSI disk controller.  After going through
my stack of Qbus boards (collected from hamfests, etc.) I came across
one that looks like it might be a SCSI controller... unfortunately,
I haven't been able to confirm it, since a google search turns up
very little on it (a bad sign...sigh)  The board is labeled:

"Emulex Corp  QD2410401-02 rev F"

It has 3 connectors and a DIP switch on the front plate. The
connectors appear to be of the SCSI-2 form factor. Has anyone
run across this critter before, or tried it with NetBSD?  Come
to think of it, Is this even SCSI, or something else
entirely?  Also, does anyone know where their might be some
on-line docs for it, or at least a description of the DIP switch settings...
