@tubetime @Stormgren Neat!
I do remember that pretty much any 13W3-VGA adapter required that the monitor supported sync-on-green — does that rule apply to this?
(Granted, I had to offload my Sun hardware 12 years ago, and don't have any CRTs anymore anyway. 🥲)
@jima @Stormgren nope you can use vsync/hsync on the 13W3 or you can populate the sync splitter chip to take the SoG and split it out into separate h and v
