Bit of an odd technical question. Any help would be appreciated.
I just recently acquired an A520 for my A500. While the picture quality is *ok* with the video (not rf out) I want a better picture.
Until I get a 1084S I have seen diagrams for wiring an RGB to SCART cable...I have also seen SCART to S Video
Now here is the question:
I live in North America were S Video is in and SCART doesn't exist much. Would it work if I made the RGB to SCART hack and then added a SCART to S Video to connect to my TV?
-
whats it like just using the composite video output?

If you are referring to the "Video out" on the A520 it is ok I just want to have a cable only method of connecting and avoid using the A520.

I think you need some sort of circuit to convert the RGB into chroma luma used in S-video. But, since you have an A520 already you can modify that to S-video. (I haven't tried this yet myself so...)

Ah ok...I did find a diagram for 23 PIN D-SUB FEMALE Amiga to SCART and a seperate one for SCART to Svideo.
In theory I should be able to bypass SCART and go RGB to S video.
If RGB analog pins 3,4,5 go to Pin 15 SCART on a RGB to SCART cable
and...
SCART pin 15 goes to S Video 4 on a SCART to S Video cable
then...
Couldn't you just go RGB 3,4,5 to S Video Pin 4?
RGB pin 10 is Composite Sync and on a SCART goes to pin 20. SCART 20 goes to pin 3 on S Video
So again couldnt RGB pin 10 go directly to S Video pin 4?
Ground to ground...
I am not an electrician or wiring expert but at 12AM my logic sounds good to me hehe
