Actually, what I would like to do is connect the XEP80 output to a PC-
style 8 pin TTL monitor input.  I think it's close; the monitor I have
lables the pins accordingly:

Red input
Green input
Blue input 
Intensity
Horiz. sync or composite sync
Vertical sync
Video ground
Sync ground

not in that order.  My first impression was to connect the grounds
together and connect them to the XEP80 ground, and take the signal
and put it in both the horiz sync/composite sync input, and the 
intensity input.  I first tried it with the standard (color)
signal from the Atari.  I got an very light image, somewhat stable,
but I'm not sure if the image I got was just being picked up from the
sync; I'm not sure if the Intensity input was doing anything at all.
I then disconnected the Atari and connected the XEP.  The screen was
just black.  I tried moving the signal from intensity to say red, and 
still got a black screen.  Any suggestions?
