Heh. I have one machine (the firewall/router) that's built around a 486 board
that although it does indeed have a monitor attached it's almost never turned
on. I can see the utility of some boxes here that wouldn't even have a
monitor attached at all, too.

I have actually a bunch of those old boards around _and_ docs for them, if
somebody needs some help with that, either in terms of taknig some of that
old hardware off my hands or getting something working. OTOH I remember well
repeatedly rebooding some clone or other while trying one jumper or switch
setting at a time and then running some diagnostic program to try and figure
things out. :-)
