If you buy the mod kit from the states I could do it. Otherwise maybe scarlet kitten could do it.

There are several ways to do the upgrade. Best is the longhorn engineer mod that uses a cd4050 and gives s-video and composite.
There is the quick and easy video mod that Only outputs composite video. The picture quality of this mod is not as good as the cd4050 method.however, it is quick and easy, requiring a couple of resistor, a transistor and a capacitor iirc

I should Also point out that these mods work great on crt TVs, but results are *very* hit and miss on LCD/plasma.
The absolute best option is to buy a French 7800 which has Rgb output via a scart connection. (That's the one, well 2 that I use)  ;)

Looks like there are no pal s-video mod kits available anymore,  so down to finding someone to do a complete mod for you.

That mod kit will do for your 7800, I would offer to do it for you but I'm in the middle of moving house and things are a bit chaotic :)

Yes that would work, it's basically the easy video mod that outputs composite video. Happy to fit that for you.

Cool, I don't mind doing it, might do one of mine at the same time.
No idea what to charge though. How much are the mod boards? maybe get me one of those as a trade for fitting one to yours?
