One 3b2 running Windowing Utilities (layers) and a 630 terminal
connected to both "console" and "contty" (the 630 can connect to
two hosts) can simultainiously monitor to 14 consoles (7 windows
per host, 2 hosts).

You might have to run your consoles going into the 3B2 at 4800 baud
if the 3B2 has problems keeping up.

Real rough:  turn off gettys on all serial ports connected to
remote consoles (in /etc/inittab)

Create two layersys files that open each opens 7 windows.
An example entry in layersys would be:

	x1 y1 x2 y2 cu hostN

Set up your Systems file to know about all 14 hosts.

On /dev/console, run "layers -f layersys1", on /dev/contty
run "layers -f layersys2".

WARNING:  I don't have a 3b2 or a 630 terminal to check out the above
claim, but the general idea should work.  One terminal monitoring 14
machines!
