Hi Rod,
is a DECServer with four or more DECconnect or RS232
ports on it.
Most of them are BNC 50Ohm thin ethernet or AUI in and DECconnect or
25Way D out. They look a bit like a hub with a BNC connector in a
depression in the top.
You're talking about a DECserver 90 L/L+/M/M+ which is very mid-to-late
1990s, to keep things in with the era you're looking at you'll need a
DECserver 200 or 300. Pity you don't need a DEMSB aka the Microserver since
I've got 3 spares of those.....
