It would have to be a Unibus bridge type device, i.e.,
it terminates
the Unibus from the CPU, and at the other end originates a Unibus with
mapped addresses on it.
Oh, right you are - I hadn't worked that out. (Probably because my head
is still full of KT24 stuff, which doesn't have two totally separated
busses. :-)
That assumes the KT11-B does only memory mapping, not
the other things
that other MMUs do (user vs. kernel mode, I/D space .. ).
I don't think it can; those would require hooks into the CPU, and there are
no signs of such, in the pictures.
