Messiah 750 for the PAL Slim 75004CB PS-2 diagrams...

[retroborg]

Hello,
I?m going to mod this ?Slim? EURO PAL PS-2 model 75004CB.
I have not opened it up yet but judging by this table:
http://www.konsolenchip.at/vers.php
I think it?s a GH-040-12 PCB.

I got this Messiah 750 Mod Chip for the V14/V15/V16 PS-2.


And these diagrams came with it:

But I?m not quite sure if they?re right?
By the way, is the ?H? point of this chip only used for the USA/JPN NTSC PCBs, same as the Matrix Infinity point ?H??

Can anybody post the right diagrams for the 75004CB model and for the rest of the PAL 7500X V14/V15/V16 PS-2s?

Any help will be highly appreciated.
Thanks in advance.

use H2O diagrams for all M750 installs

H20?
Got any links?
Thanks.

So could I alternatively use these diagrams:

H2O Chip

Instead of these:

Someone mentioned that it is not need to connect point “Z” on the PAL 75004 Slim PS-2 as that point is only needed for the multi CD games and it could cause problems, but I’m not sure about that?

Also I noticed a few differences in the operation of the two chips:

Messiah 750 operations:

H2O Chip operations

Would the H2O Reset operations work for the M750 as well?

Thanks in advance.
