There is also a "BA11 expansion box sided"
box from Plessey, but
I have not yet looked at the details of the machine, so that
Plessey box is a black box to me at this point.
Plessey made various Unibus (and Qbus?) devices that were more-or-less
DEC compaatible. At least one of the RAM boards in my 11/45 is a Plessey.
I also have a PLessey 10.5" high expeansio box on that machine. It's
nicer than the DEC one in that you can fit 3 9 slot backplanes across it
(or 6 4 slot). The power distribution is non-standard (9 pin mate-n-locks
for each backplane) but that's easy to sort out.
