Most TVs back then had at most a CVBS input. S-Video came later. So a home computer with RGB out would have been overkill. I do consider it quite an achivement that MOS had video controllers that produced S-Video on die and needed only a small driver circuit per signal to be ready to use. What other low cost video controllers back then had that? > However it is true that e.g. > Acorn Electron has a TTL RGB output just like its big brother, the BBC > Micro. RGB needs more pins and if your output is 40 chars per line, S-Video is plenty good. Unless of course, you have a crappy modulator in the signal path that does horrible things to your signal. From a C64 forum I got a small circuit (2 transistors plus a few passive components) that one can use instead of the modulator. You get S-Video only at the output then (no CVBS anymore), but the picture is really good. I haven't tried it on a C16 yet, but I see no reason why it shouldn't work there too.
