It's actually a MXV11-B Multifunction card, with 128KB RAM, and ...

Or maybe 256K

... the MXV11-B has two SLUs, of the same type as a DLV11. It also has a
bootstrap (usually) which is vaguely similar to some of the 11/23+ ad early
11/73 bootstraps, and an LTC. And a million jumper posts. I have a
document listing their names/functions somewhere online, if you need it.

Well, the one on the left of the card, looking into it from the back, is
the console line, if that helps.

Well, that should be running. As Tim noted, there isn't a disk controller
in your list, though. I'd expect an RQDX1 or maybe RQDX2 in that machine
-- more likely an RQDX1 if the drive is an RD50. If there isn't, it won't
do much. It might be worth trying to connect a terminal to the console SLU
and seein what happens when you start it. You can break into the bootstrap
routine using ctrl-C if necessary.
