Hmm, so strapping pin 7 to pin 10 on the video connector isn't enough to
kick it into 640x480 mode like it is with various other Apple hardware?
For the 512x384 mode it's certainly not within VGA spec, but I know the
system is capable of 640x480, which I'm assuming should be. I'm currently
wondering if it's outputting composite sync, though - everything I'd seen
suggested it was either SoG or separate h/vsync, but maybe that's wrong and
