I think also that SGI uses sync-on-green (probably only the three 
coaxes, yes) and Sun uses composite sync, that is horizontal and 
vertical on one wire. (PeeCees typically use separate sync wires for H 
and V I think.)

Pinouts are available with a little Googling, but it always takes me two 
tries to get it right, and those connectors are a pain to solder.
