The BDV11 shows all four LEDs on, and the RUN LED does blink momentarily
but then goes off.
So it's trapping immediately on startup. Either the CPU card is bad
(which I know isn't true) or it can't find any addressable RAM, or it can't
access the console SLU registers, or something is inhibiting the LSI11 from
running at all.

Yep. And the same boards except the CPU, work in the same combination in
the BA11-N with a 11/23 CPU card. [It's one of the half sized 11/23 cards -
KDF11-A - without the onboard SLU and ROMs]

If you mean the rev level, that I don't know off hand. It's one of the
ones with no actual onboard RAM, though (it has the space for it; the RAM
chips just aren't populated).
