It also helps to manage many of them in larger cabinets.
In 1991-1992, we added self made ISDN boards to the Boot-Prom socket of
Sun 3-50s, put several of them into a Sun/3-160 cabinet that then was put into
the computer room of the TU-Berlin as a ISDN<->IP gateway for students.
There was e.g. a cabinet with the machines named "fa", "so",
"la" "si" in the
domain ".isdn.cs-tu-berlin.de".

and shove more VME stuff in there. If the 3/50
was a VME board I'm not
sure what the point was other than, perhaps, to reuse the same part in
a small case. I can't see Andy doing that, he was super cost sensitive.
Unless you're planning on selling lots of them, using the same PCB and
just not populating the bus interface logic might be cheaper than
designing a new board.
