Hi, I'm buying one of those firewire cables for my sony camcorder, buy I don't know whether to buy a 4-Pin to 4-Pin or 6-Pin to 4-Pin cable for my iMac G3? Can someone give me like a picture of them both or something? Please? thanks. I'm trying to find a picture on google right now. I'll update if i find it. But please help! thanks!
