My home network is a 10-megabit Ethernet consisting of:
The hubs, with the notable exception of the Boca, are connected via coaxial cable. The coax provides connectivity for the VAXen and the HP. Everything else runs off typical category 5 cable.
Internet access is provided by a shared dialout connection on the G4. It is running ipfw and natd (Mac OS X provides these out of the box). All I have to do to get a machine on the 'net is to set its default gateway to the IP address of the G4, and off you go.
The DECserver 200/MC provides a console for all the VAXen. I can set up virtual connections on it, and use my VT-420 as the console. This saves a lot of space.
My plan is to get the SCO box running BIND, LDAP, NIS, etc. All the back-end services that make a network easier to use. It's still a pain to have to set up hosts files for each box. DNS would be a much more elegant solution. Right now, my laptop is providing MOP remote booting capacity for the MicroVAX 3100. I'd like to move this functionality to either the SCO box or the HP 9000. I had originally planned to use the VAX 11/750 for this, but I'm opposed to running BSD on it (preferring to run VMS), and I don't have the needed skill with VMS administration to get all this running. UNIX just seems to be a more natural choice for such services.
