I just don't understand why it has a 9 pin connector.
I'm sure NO VGA card ever did. And apple's were all 15
pin (like old ethernet).

What were you driving those with? They readily worked
with Macs, indeed many were "Mac" monitors (RasterOps,
E-machines...) or rebadged Sony OEMs. I remember guys
running out and buying 486 mobos with PCI slots so
they could plug in a fixed frequency card (SVGA, but
everything came out usually @ ~64khz). With alot of
those cards in the mid to late 90s, you could play
with the refresh and sync polarities to your heart's
content, so you could get some functionality with a
standard SVGA card. Occasionally something was funky,
in my limited estimation the video signals were too
narrow (or wide) or something. I first learned of this
stuff from a book by this guy from New Hampshire ("the
Cheap VGA Book", not so wisely named). But most of
what he talked about were earlier models that worked
with base VGA frequencies (31.5khz). Never found one
of those. Johnson I believe was his last name.
