Schematic for Playstation scph-1001 needed

Hello guys, I wass curious if anyone around here knows the workings of the SCPH-1001 motherobard as I'm going to be installing an S video port so I would not have to keep using the proprietary S video cord for playstation. Question is where are the points on the mobo for S video? I believe its very similair to the SCPH-1000 PU-7 board. My MOBO is a PU-8 board.
