[rescue] SOG converter

If this is for an SGI, unless I read the pinouts incorrectly, SGI does
provide a composite sync separately from the sync on green... they
use a different pin in the 13W3 than Sun does though.

Maybe not all SGI's provide this signal though ?

Anyone have any real world experience with this ?
