Oh fun, I bastardized my own cable by cutting an apple 13w3 in half and
splicing 5 BNC connectors in.  Does anyone have any documentation on the
different 13w3 implementations?  I was thinking the monitor couldn't keep
up, but maybe it is a cable issue.  Of course my wiring pattern should
have ended up with the right connections anyway, I used a sun 13w3 to HD15
pigtail, and an HD15 to 5BNC cable, and just wired my cobble job to match,
so I should have eliminated any Apple quirks.

By the way, I'm not a monitor guy, but this cable "works" except I get two
images of the screen side by side, am I right in assuming the monitor has
synced to half the horizontal frequency?  It appears I am getting two
scans accross the screen, but there don't appear to be any visible
retrace, which I would have expected.  The monitor isn't known good, and I
haven't tried it with my peecee because it has to be manually synced, and
it's a nuisance to take it apart and tweak it.
