I suppose on a real II the colour killer doesn't kick in for the middle text section, but it looks almost as Bob intended.That depends on how the TV deals with the loss of the color burst, as Michael was discussing. This emulation currently produces monochrome pixels on any line that was in text mode during the burst time.I can guarantee that no analog TV ever switched modes in less than 16 milliseconds.
Oh yeah I wasn't doubting you Michael, just describing what my code currently does. I'm planning on making a change there soon. I have wondered before why the Apple II doesn't kill color in the text window at the bottom of graphics screens and now I know. Also I can report that the text section of the Money Munchers intro on a real IIe is color fringed. I also looked at it again in NTSC Applewin and the first few lines of the text section are drawn in color as are the last few, so the video mode is graphics for at least part of the color burst cycles on those lines.
