How big is a PDT-11/110? My PDT-11/150 is quite a bit larger than a
DECmate III.
To the best of my knowledge the smallest possible PDP-11 made out of
real hardware would be a 4-slot dual-height backplane, with a
dual-height CPU (ideally a PDP-11/73), DLV-11J (providing console
port), 3rd party disk controller w/bootstrap (preferably SCSI). That
would leave room for one additional dual-height board. You'd have to
figure out the power-supply and how to wire up any disk or tape
drives. I'd build something like this, if I had the backplane, but I
don't.
The smallest DEC PDP-11 that I'm aware of is the PDP-11/03, but
you've got to add a external drive of some sort.
For people where a system the size of a BA23 is an issue, your best
bet is going to be to simply run under emulation. In my case it
isn't the size of the systems so much that is an issue, it's how much
space all the documentation I have takes up!
