Um, I seem to have rushed in a bit quickly. The AT&T board works with composite video color monitors, but it also works (according to InfoWorld's report and ima!johnl's private communication) on digital IRGB displays by "flickering" the colors on and off to simulate levels of brightness. Good stuff, if it works (and doesn't fry your monitor!) -- /Steve Dyer {harvard,seismo}!bbnccv!bbncc5!sdyer sdyer@bbncc5.ARPA
