OK, I got plenty of answers. Let me summarize...the summary:.
master -- system with monitor+keyboard,
slave -- system with no monitor+keyboard
Option #1: Serial Connection.
As I mentioned in my posting, I dont want this solution because
eventhough it is cheap and feasible, it makes the slave to be dependent
on the master. If master is down, slave aint coming up.
Option #2: X Window displays
IMHO, not feasible. Yes you can do everything with X when all is ok; what
happens when the slave is at the boot prompt?
Option #3: Buy a switch
There are out in the market switches that do this. This is actually the
most correct, and professionally sound solution, but guess what? -- it
costs. From my brief survey the prices can range from $1,800 -
+oo...depending how funky and how many ssystems you want to control
with one wsitch.

Not a clean solution perhaps, but why don't you just run X windows
(OpenWindows) and log into the other system? If the other system is not
running X, then you can attach a serial-port connection for the second
system and 'cu' or 'tip' your way into the console of the other system
from a shell window on the first system.

well as PCs..we have an eight-port model here for our suns and are
thinking of getting an expantion for it

Is there any reason you can't use X?
On system 1: openWindows or CDE or X11 running whatever apps you want
xhost +system2 set so that the other machine can
use your display
On system2: get to system 2 by telnet/rlogin from system1. set the
DISPLAY variable, eg
setenv DISPLAY system1:0.0
run whatever applications you want and view the
display on the screen of system1

Black Box makes a simple switch box that can supply different input to
one output or if connected in reverse, supply multiple output to a
This might not be useful on Sun systems with intelligent video detection
circuits that kick-off when there's no video detected.
Other companies provide "single console" boxes that intelligently allow
you to have a single monitor and keyboard/mouse for upto 60 Sun
computers, and they maintain a "video detect" on all channels at once,
while only displaying one at a time. Typically these seem to be in the
2000.00 + market.

Have you tried two xterms, one from each system, on an X server on one
of the systems?
This won't work at all, of course, for booting the system or running
single-user: only once the systems are fully booted.

Yes, you need to buy a video switch box. It will have an A/B switch where A
goes to system A video cable and B goes to system B video cable. The center
cable will go to the monitor being shared. I think I bought mine from BlackBox
or something like that. Hope this helps.

It depends upon how fancy you want the solution.
I just have a single monitor that "services" 3 different
Ultra2s. I plug the monitor into the system that I want
to "see" & move the cable to the next system when I
want to work on it.

Check out Lightwave Communications. I don't have a url
but you can call Judy Jovanelly at 800-871-9838. I was
looking at PC and SUN monitor and kbd sharing. They have
a few solutions.
If you want, I'll find the url. I got it out of a
SunExpert issue. Let me know.
