Ahh - it's for a PAL system. I should have read your first mail more closely. There was a v1.12 for JAP and I didn't notice your version 4 statement. Sorry. The stuff I sent is strictly JAP 10000/15000. the boards are different. You'll need to take the diagrams from the www.origachip.com site for v4 PAL. I'm sorry for causing you delay.

To read what I've done, you'd need the Adobe Acrobat reader.

The CPU pins are the same as between JAP and PAL PS2s but the location might be different.
