I'm working on a mostly useless Mac-to-VGA adapter prototype with integrated sync splitter, and I could use some testing help. If you have one of these Macs or video cards:
I am interested in getting direct proof of which systems output CSYNC only, and exactly how the CSYNC signal looks, and which systems also output separate HSYNC and VSYNC signals.

- LC I
