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.
