Even better: If the monitor is a VRT19, it has everything in place for the
H-/V-sync lines but the BNC sockets and the two holes in the back plate.
Remove the back and you'll see that (and about a dozen knobs for adjusting
all sorts of aspects of teh screen display). I upgraded a VRT19-HA (Sony
GDM-1961) with two BNC plugs for use with a Macintosh Quadra 700 that way.
Later, I found out that the Q700 and the VRT19 can both do sync on green...
