I just about got killed one time when I turned off a guy's monitor
from software.

On 128k machines it is possible, with correct coding, to boot a machine
into the aux memory.  Sound and video soft switches work fine, and if
the game or whatever doesn't require aux memory it'll usually run fine,
too, except that the screen keeps whatever was on it earlier.....

I booted karateka and he could hear the game playing but no picture.

try this: put a program on a disk that clears the screen, waits for
a keypress, pauses for about 5 mintues, and then starts flashing the screen
from inverse to normal and back.  Then run around to all the lab
computers and load it.  Now casually walk the perimeter of the lab, tapping
the space bar on each computer in turn.

alternately, write a program that when actuvated, waits 5 min and then
beeps randomly, every 10-100 seconds.  That one is even more fun!

Computer teachers think the room is posessed.....
