S-Video Mod Screens

I've modded my C64 to add an S-Video output. Here are some photographs showing the results:

As you can see, the picture is very sharp and crisp. It makes reading the graphics, particularly on the Monosynth, much easier, and is a good deal less tiring on the eyes. The television used is a Philips flat-screen.

Re: S-Video Mod Screens

Yeah, it's good.. I've done the same thing, plus that I've put a potentiometer on the chroma signal, so I can lower the amount of color sent to the TV (to cure bleeding colors..).

Re: S-Video Mod Screens

Yeah, I put a trimpot on the line in there as well.

I'm going to tweak it a little to try to get a better picture on CRTs.

Re: S-Video Mod Screens

I thought of it after I've already put the pot there, that a trimpot would have been better.. But I'll stick to the ordinary turn potentiometer for now.. smile

Re: S-Video Mod Screens

Here's the back of the C64, with S-Video socket (4-pin mini-DIN) and 1/4" outputs for the 6582s.

Re: S-Video Mod Screens

I also did a conversion:

Another upgrade: s-video, component & audio

But the thing is that the picture quality is not perfect, shall i desolder the din8 female plug and solder directly thicker wires to the PCB?

Re: S-Video Mod Screens

Looks good Berry.

You don't need thick wires for the video signal. But do check the integrity of the connections with a multimeter if you have one.

Do you have any pics of your screen running MSSIAH?

Nice work there.

Re: S-Video Mod Screens

I wonder, does this offer more than a cosmetic improvement over leading chroma and luma directly from the VIDEO port?

Re: S-Video Mod Screens

No, it's the same.

Been quite a while since I posted all this! The trimpot has been removed as I found it was unnecessary.

Re: S-Video Mod Screens

BTW, I see you have monojack sockets on your c64. smile Did you implement some sort of protection?
