About one month ago, I posted to ask
"how to turn off a ( monochrome) NeXT station's screen"
I received several answers. ALL of them told me that's impossible to 
turn it off completely.

But now I encountered one thing which makes me reconsidering its possibility:
One user turned off my color station WITHOUT turning off the its power.
Since I don't know any command that can bring it back, I power NeXT down,
then up, to turn ON the monitor. (rebooting doesn't turn it ON).

So I have 2 questions:
1. how was it done? That guy used some magic that I'm not aware of.
2. If it can be done on Color, can it be done on Mono?

Color stations have a separate power switch on the monitor.  So all he did was  
to turn off the monitor.  The CPU continues to run fine.  (We do it all the  
time.  You can just turn the monitor back on and everything will be fine.  (At  
least, if you've logged off before turning it off.  I don't know if everything  
would be fine if you were logged on at the time.))

Not that I know of.  There's certainly no separate power switch.
