2) Popcorn (slowdown/acceleration, manual palette switch)
Funny that you mention Popcorn.. 🙂👍
I've used it for testing purposes a while ago..
Popcorn uses an alternate palette already (red vs pink).

4-greytones would be nice.
Yeah, sometimes our eyes hurt so much we'd wish CGA had no colour..
With a real CGA and a video monitor (mono or PAL) it's easy to get rid of colour..
Or just use a VGA adapter that grounds pin 12 (mono monitor sense), so the VGA card goes monochrome.
Or use this: https://hackaday.io/project/166041-monochromevga
(Makes me wonder if that works with SCART, too. Take CVBS/VBS video and feed it into both
Green and Composite Sync, use a 3v coin cell to activate RGB Sense pin.. )
Edit: It's possible to turn any CRT TV/CRT video monitor in a monochrome display.
It's possible to manually adjust the potis for R/G/B on the driver board.
The colours not wanted can simply be turned down.
That's better than for the circuits than cutting off the R/B tube terminals if you want a green monitor.
