PS1 motherboard

Hiya

I just wanna know if anyone knows where i could get some info about the circuit scheme of the PS1. The model I want to know about is  SCPH-9001. It's a North American model for your information.
So please I hope anyone could provide info about it, hopefully through a link or anything similar.
My purpose is to try make something of the motherboard of one of my old units.

Google is smarter than /tech/.

I should add that I've tried Google.

If you've opened it and don't know what you're doing, go to RadioShack and buy a few beginner kits. Srsly.

btw, it's "schmatics", not "circuit scheme"

ah fuck. schematics*
