Connect the C-Sync signal from the Sun via an 330 Ohm resistor to the
green signal. This will generate Sync-On-Green. If you are familar with
a soldering iron you can solder the resistor on the bottom side of the
GX PCB directely at the connector. Maybe you have to break the 10 extra
pins in the 13W3 cabe, because the SGI monitor may ground the pin that
caries the C-Sync signal. The pinout for the coaxial RGB-Pins is the
same on Sun, SGI und IBM.
