PS2 Modbo 4.0 90001:Possible Error in Some Install Diagrams

Hi all,

There seems to be a mistake in the Modbo 4.0 install diagrams (available on the web) for some of the 9000x units. The 9000x has a few variants, mainly the two boards GH-071-42 & the GH-072-42.

Prior to installing a modbo 4.0 on a GH-071-41 yesterday, I compared the two install diagrams of the 2 variants: GH-071-41 & GH-072-42, and they're almost identical in terms of board layout. The only different connection was the point "CX". I found that odd, since the layout in the area appears to be exactly the same, with the same components on both builds. So I wondered if it's not just another mistake (there's also a mistake for some other pin for the V7: 39001 units as well). Anyway, I soldered the "CX" point per the GH-071-42 install diagram (which is the board I have), and everything worked except backup DVD9 games (I don't have original DVD9 games, so not sure about those). I changed the "CX" solder point per the GH-072-42 diagram, and that fixed it.

I soldered the "CX" wire back and forth, between the two locations twice to validate the findings, and in both cases, DVD9 backups won't play (stops at the browser screen) per the connection point of GH-071-41, and DVD9 backups would play per the connection point of GH-072-42, even though it's a GH-071-42 board.

Example of install diagrams with the mistake:
GH-072-42
GH-071-42

Other sources also had this mistake.

I couldn't find any info on the web, so I thought I'd add this here just in case someone else may run into this some day.

thanks!
