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.

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.

Ah, I thought you had a BA11 and were going to put that in some kind
of table-top enclosure which had the bulkhead holes in it. I must
admit, I was kind of wondering what that was. Does the BA11 you're
looking at have a cover? On mine, the cover is actually also what
holds the thing in the rack; the chassis slides in from the front.

The BA23 panel is a very different shape, I'm afraid, and there's not
an awful lot of clearance behind the BA11 panel for bulkheads. You
might just get some to fit if you can fabricate a suitable panel.
There may be enough room to mount some ports at the bottom of the BA11
panel if you remove the sliding adjustable parts. Or how about just
building a couple of homemade adapters/cables? For example, an IDC
connector at one end and a DE9 or DB25 at the other for the console.
And, of course, you can get one BA23. But I have the
BA11 in mind (by now)

An actual BA23 is indeed very handy to have around. Which parts are
you looking to reuse?
