Do note that this board is designed for converting arcade gaming machines to VGA... not PC digital CGA (RGBi) to VGA. Arcade machines run at television RGB (~15.7khz). In fact, you can use an arcade monitor directly with the IIgs.. and I'm thinking of going that way... since arcade monitors are available in 15,17,19 inches and larger (if you're crazy).
