I am not sure what other UNIBUS cages there are out there, but I think
and UNIBUS cage would probably work. They seem to be prity self contained
and just paddle connectors. From memory only th 11/7xx and 8600 series
realy used UNIBUS.
How are you going with getting hold of a system cabinet? and/or backplane?

I am in Australia, over here last time I tried bidding on a uVAX II, that
completely crazy! When as high as $700 AU, about $1400 US.

As I  understand the MASSBUS on the 11/785 is just a couple of slots in the
card cage in the system cabnet, far right hand site.
The cards I have heard you can get for it are Disk/Tape controlers  and HSC.
MASSBUS is genraly perfered to UNIBUS for speed reasons as it is full system

There is some more info in the 11/780 and 11/785 Installation Manuals that I
have, that I can scan in if you are interested. Manly only things like
pictures of
the cabnets and layouts.
I just thought, you would need to source a LSI-11 console as well?
