Messiah Version 3 Main Board Installation Diagrams
I have verified that the following installation diagrams below will work with all New Zealand released Version  3 main boards. The Version 3 main board will normally be fitted in the SCPH 30002. Please note there are 3 variants of the Bios chip. Please ensure that you use the correct diagram for your version of the Bios.

Configuration Jumper Settings  

 

Important: Do this first before you start your install. Ensure that you solder all 4 jumpers. Failure to do so may damage your Messiah chip.
 
Messiah Connection Points  
Pictorial view of the Messiah connection pads and the associated points on the Bios and Controller chips. Use this diagram to check and recheck that you have soldered the wires to the correct points. 
 
Messiah Location on the main board - Top Side of Main Board

 

The Messiah is stuck down with double sided tape onto the open space on the topside of the main board. You can't miss it - it's the only bit of real estate left where the chip can fit nicely onto the main board :o)
 
V3 - Power and Ground Connection Points - Top Side of Main Board
 
Both of the connection points are located on the top side of the main board. Use light hookup wire for these two connections
 
SCEX Connection Point - Bottom Side of Main Board

This connection point is located on the bottom side of the main board. You have to remove the 4 machine screws that hold the heatsink in place. Remove the heatsink to expose the SCEX connection point. Use 30swg wire wrap wire for this connection and feed the wire through one of the holes in the main board, but not the screw holes for the heatsink!!! Click here to see a photo showing the SCEX connection and the hole it is routed through.
 
Bios Chip -  Top Side of main board

This Bios on the top side of the main board is generally in the earlier releases of the PS2's in NZ. It is located over by the Expansion Port connector. Use 30swg wire wrap wire for these 9 connections.
 
No Gap Bios - Bottom Side of Main Board

This Bios is located on the along one of the edges on the bottom side of the main board. Use 30swg wire wrap wire for all 8 connections and route the wires through one of the hole on the main board so they appear on the top side. The 9th connection "W" point is located on the top side of the main board, see diagram further down.
 
No Gap Bios  - Bottom Side of Main Board

This Bios is located on the along one of the edges on the bottom side of the main board. This is generally associated with the later versions of the SCPH 30002 models. Use 30swg wire wrap wire for all 8 connections and route the wires through one of the holes on the main board so the appear on the top side. The 9th connection "W" point is located on the top side of the main board, see diagram further down.
 
"W" Point for the Gap / No Gap Bios - Top Side of Main Board

This "W" connection point is ONLY for the Gap and No Gap Bios that located on the bottom side of the main board. This W connection point is located on the top side of the main board next to the Expansion Port connector. Use 30swg wire wrap wire for this connection.
 
"R" Point - Top Side of Main Board

This point is located over by the Controller chip on the top side of the main board. Use 30swg wire wrap wire for this connection.
 
Reset Point - Top Side of Main Board

This connection point is locate along one of the edges near the corner that has 4 large holes on the top side of the main board. Use 30swg wire wrap wire for this connection.
 
Controller Points -  Top Side of Main Board  

The Controller chip locate by the group of 3 connectors in one corner of the main board. Use 38swg enamel wire for the 8 connections to the Controller chip and 30swg wire wrap wire for the "A" point connection. Ensure that you have the experience in soldering to surface mount components before you even consider attempting to carry out these connections. 
 
RGB and NTSC-PAL Fix - Top Side of Main Board  

RGB Fix: (top part of the diagram) is required if you intend on using a SCART/EURO cable instead of the standard AV cable. SCART/EURO connectors are general more associated with the Europe/UK TV systems. If you do not do this you may end up with a grren picture on your TV when viewing DVD movies. I only do this if customer wants it.
NTSC-PAL Colour Correction: (bottom part of the diagram) is required if you intend on play NTSC (USA/Japan) games or view NTSC movies. Simply just solder across the 2 pins. I do this as standard on all installations. If you do not do this fix NTSC games will be displayed in Black and White on PAL TV's unless you have a nice NTSC compatible TV system :o)
