Hi all; I am having difficulty getting RGB output from the 80 column extended RBG card in an apple IIe. I get a black screen when a standard RGB monitor is connected. The connector is putting out composite signal, that I am sure of.Trying different monitors, I found one that has the skewed composite output. Output is normal on the composite connector, both in 40 and 80 column mode. Is there a control, or escape sequence that will switch the output to RGB? I have no documentation.
You might want to check whether the pinout of you monitor cable has any relation to the pinout of the RGB card. This was always a poorly standardized area. I assume you're using a digital RGB monitor... -michael Music synthesis for 8-bit Apple II's!
