because of the extremely CISC arch, they don't need a whole lot of memory to
be efficient, although i've found that NetBSD needs quite a bit more memory
to be useful than VMS does.

actually, i think the BA23 rackmount is only 3U.  although i think they look a
lot better in the deskside pedestal: www.arkham.ws/complab/pics/PDP-11_23.jpg

i think the best part about that case is that there are far more QBus slots
than you would expect be in there.  very compact case.  very very nice.
