Does anyone know anything about the CRT controller? Maybe it can be reprogrammed for a cheapo monitor? Lots of time to work this out before the supply dries up, but let's not wait until it's too late... Hundreds of stores, catalogs, discount houses, etc. advertise $50-$70 monitors for use with "Hercules" graphics (720x348) for "IBM-PC"-like systems, with a choice of paper-white, amber, green, and other phosphors. Should be NO problem at all hooking up one of those to the 3B1's video signals; I've been thinking of doing this myself for two reasons: 1) I intensely dislike the (present) green phosphor ... the color reminds me of something I heard of 30+ years ago when I was a kid: "Goat Vomit Green" (contrasted with "Pygmy P*ss Yellow" or "Baby Sh*t Brown" :-), 2) I'd prefer a 13-15" screen, and (yeah, I can't count :-) 3) I'd like to hook the video signal into one of those LCD-screens for use with an overhead projector for room-viewing of the 3B1 screen's display. I may just try this during the upcoming holidays. Looking at the video signal timing, there's NOTHING special about the 3B1's video. Some eleventy-seven million "IBM-PC"-type systems also use Hercules graphics monitors. Just put a DB-9 connector on the case and plug a video cable into the monitor.
