Thanks for making me pause before rushing down & buying a cable, & also
making me aware of the sunhelp site. I will do some more research.
BTW, only 6 of the 9-pins are in the port on back. Pins 5, 7, & 9 are
missing (presumably not by damage). For what it's worth. It could well be
composite sync, then, because according to the pinout FAQ at
<http://www.monitorworld.com/faq_pages/q17_page.html>, 9 was for vert. sync,
& 8 for horiz. or comp.
RasterOps made 2 TTL video cards in the late '80s, according to their chart
(<http://www.rasterops.com/Display_cards/display_cards_FAQ.html>). 1 for the
SE & 1 Nubus (the CV II). No word on what resolutions they supported, tho'.
All the best,
