Welcome to the forum Jesus,
The cable you are seeking is a Firewire Cable and if you click on this LINK you should see a picture showing the connectors on the cable.
Of course you need to check your PC and Camera to but I'm certain the camera end is correct because I have used this on my Sony Hi-8
Hope that helps
OOOooops!!!

Jumped the gun a bit there, sure the firewire cable will fit your PC BUT not the Hi-8 camera. My apologies for that . My only excuse would have to be that I have several different cameras here and my brain was not properly in gear
.
To go from Hi-8 to your PC you will need some form of analogue - DV convertor to use the Firewire input. Maybe someone on the forum could recommend a suitable one to use as I haven't used one for quite a while. When I need one I use the passthrough facility on my Digital-8.
