Right. The only thing is that what's good for text is not so good for graphics. On my VGA the sky looks like blue and black vertical stripes which is not surprising. On an NTSC TV it looks solid blue as the lines merge due to low color resolution. Interestingly if I switch the Amiga monitor into separate luma/chroma mode and do not connect the chroma line at all, there is enough 3.58 signal bleeding through to color it up at a low saturation and the vertical lines are clearly visible. The color saturation knob is the key. Set differently for games vs. text.

If the IDE connector is not used on Carte Blanche, the two rows of 0.1" spaced pins provide a nice space for configuration jumpers so we can switch between 3 modes for "hi-res" graphics: full mono, current mode and filtered mode closer to a TV: if 2 dots are the same color separated by a black dot, all three are the same color.

Or we can make soft switches triggered say by writing to not normally writable space, for example C3xx.
