[Coco] S-video Prospects...

[Stephen H. Fischer]

Hi,

Very Interesting! A good refresher on stuff I learned long ago.

I am still wondering about what I see on my "P0001798.jpg"

which matches what  Chris Hawks said:

But my "P0001785.jpg" does not show the leading border.

It may just be the camera angle. On the other text displays it is harder to
see.

I wonder if setting the border color makes any difference. (I forget the
Pokes).

On my RCA TV, that is not possible (Without the Service Manual).

The only adjustment that I ever make is to lower the color which the
factories set high "Because you should see the colors if it is a Color TV"
to sell the sets.
I get sick in TV showrooms with so many bad settings of the color!
