Agreed. This is geting a bit off-topic[1] but that's the sort of thing
VLANs are for. You could use an intelligent switch (or hub) and put all
the NT systems in a separate VLAN from the Unix boxes. Some systems (eg
Enterasys/Cabletron) can do that for you automatically by seeing what
does/does not generate certain protocol packets. A VLAN is a single
broadcast domain, so the broadcast to the NT machines will be restricted to
the NT machines, never reaching the Unix boxes, regardless of subnet
numbers and network topology[2]. We've been using VLANs for similar
purposes since 1995, though in our case it's mostly to restrict Appletalk
and IPX to a range of ports (spread around several dozen switches and hubs)
and to separate staff, student and management subnets. Recently I've also
put the DHCP servers into a separate VLAN, and restricted the connections,
so no-one can run a rogue DHCP server.
[1] VLANs are too recent (mid 1990s) to properly be the province of
classiccmp.
[2] Of course, you could also do this by assigning all the NT boxes to a
separate subnet if you have a spare number range. The advantage of VLANs
is that they can overlap; machines can be members of more than one for
different purposes.

Does anyone have or know where I can get a copy of the game "Combat" for
the TRS-80? It was a multi-player game that allowed you to connect up two
TRS-80s and play against another person in realtime.
If so, please contact me directly <sellam(a)vintage.org>.
Thanks!

I'm totally disgusted with DECUS/Encompass... I think someone pulled
a fast one on the membership. I understand there were two votes
recently. I got my ballot for the first one... I didn't get a second,
so I sent email to the location specified on the encompass web page.
I never received the second ballot, and after the deadline had
occurred, I got mail back indicating it (my email) had gone to
the wrong place (I would have expected the mailto: link would
have been set correctly).
Anyway, at this point I don't care... DECUS is gone. I don't know of
anything to bring it back. I won't be renewing with encompass, it doesn't
meet my needs at all.

Not quite; they're static-column, not FPM.
I was going to reply that two of these would make a buffer for my Z80 EPROM
programmer project, but I wasn't planning to build 150 of them!
Anyway, I see others have beaten me to it :-)

Just picked up a Commodore 286LT notebook (1990, so it just makes it!). Has a connector for an internal modem & two internal plugs for ram expansion, can anyone on the list tell me where I might find this items ?
(And docs for the machine.....)

And it invariably wants that relatively little power to be delivered

Ducky.
But don't mind me, I'm just irked because R*d H*t L*n*x 7.0's de4x5
driver doesn't seem to want to grasp that there's a BNC connector on
the card, let alone that that's where the network is connected, so
there is now a hunk of Cat5 leading to a shiny new hub (with BNC
connector) sitting on top of that box, and a new wall wart occluding
two outlets on the power strip.
ObClassicCmp funnies: maybe it's just that my Un*x preferences run
along BSD lines (with the exception of HP-UX version 5 on 9000/500s),
but R*d H*t sure makes me think of the old joke about AIX: it's like
what a Martian might do if his buddy returning from a survey of the
blue planet told him about this really neat operating system called
Unix that they use over yonder.
ObClassicCmp2: so how many Thicknet folks actually have the tap
installation tool? You know, the one that looks like a drill bit mounted
in a plastic handle?
