Ok, if I remove the SPX graphics board for mono video, what are the pinouts
for the video?  I assume it is still sync on green.  I can get a picture
with just the green line when I have the SPX video in on Pin 10.  However,
without the SPX card, I get nothing on aany of the pins.  Does one of the
jumpers on the mainboard toggle SPX graphics on or off?
