Hm, I need some more English pratice again, it seems. 😅
What I meant to say:
Television Sets with SCART connectors can handle the 15KHz RGBI signals from the CGA card's DE9 connector almost directly.
There's a simplistic mixer circuit involved, and a few resitors here and there, but in general, it needs less modification than VGA's RGBHV input @31KHz
What I also meant to say:
PAL/NTSC colour coding doesn't matter if RGB is used on a PAL TV set. Or NTSC TV set.
Futhermore, there are two kinds of Composite CGA:
a) One uses the colour burst signal to generate colors on NTSC 60Hz TV sets.
b) The other one uses special patterns (lines, circles, etc) to trigger artifact colors on classic American tube TVs.
The artifact thing works best with lossy connections, such as Composte or RF.
Hence I recommended using a Composite-> RF conveter and an oldschool NTSC TV (cabinet made of wood, metal etc).
Edit: For completeness. I meant to point out that IBM's CGA followed signaling and resolutions of the Televisions standards of its time.
CGA was made on purpose compatible with them, so common thrid-party TVs and monitors could be used by end users.
And yes, it's true, Euro SCART can handle both RGB and CVBS (Composite), in fact, the monochrome (VBS) part of Composte is often used for syncronisation.
S-Video (falsely also known as S-VHS) came late to the party and was the old Chroma/Luma combo, in fact.
Albeit with a little bit different electrtical characteristic, if memory serves (have to check).
Because of that, and Euro SCART cables can either carry S-Video/Composite OR RGB/Composite, but not both.
Edit: Typos fixed.
Edit: One more. 😀
When people talk CGA composite, they generally mean CGA NTSC composite. Most SCART TVs are PAL, which doesn't artifact the same way.
Yup, 30 or 40 years ago, it was like that. If memory serves, SCART TVs of the last ~25 years or so were multi-norm all the way, though,
at least on the Composte terminals (not the tuner), since they were being made in the far east, anyway, were all standards
were used by each one's neighbour (China used to use PAL, Japan NTSC etc.)
