I've got a spare 3m S-Video to Scart cable that I don't need as my new graphics card is 7-pin. This is the cable you use to connect your PC/Laptop to your television, just plug one in into the tv-out socket on your computer, and the other end into the scart socket on your television.
The plastic bit at the top of the connection (if you don't know what I mean, look at this picture
, it's the little black bit between the bottom two pins) has broken off. This doesn't affect it's performance at all since it's just a bit of plastic (think of it as the plastic connector on a 3 pin plug), it just makes it a bit easier to accidentally pull out. I've never found this a problem, but I thought it was worth mentioning.
Looking for £5 delivered for it. Picture in next post.
