You're right. I got one photo of the back side of one BA11-SB and it's
exactly as you describe it.
Options ? Doing some homebrew would be possible to replace the back cover
with one bulkhead of, perhaps, one BA23 :-)
And, of course, you can get one BA23. But I have the BA11 in mind (by now)
and I need to reuse some BA23 components.

Sorry about that -- I forgot that the BA11 doesn't have those
bulkhead openings on the back door.
Let me guess -- the back door is just a solid piece of metal,
with a small adjustable slot towards the bottom, to allow
cables to pass through. . .
If that is the case, then what you would do is to obtain
one of the metal bulkhead frames that they use for
expansion on the q-bus & unibus boxes.
It's basically a rack-mountable metal piece,
with a bunch of bulkhead openings on it.
I don't know the DEC part number for that,
but someone with a DEC Systems & Options catalog
from say. . . 1986 . . . would be able to help you.
