Can someone identify this PS2 v10 modchip?

Hiya!

I got from a friend a ps2 v10 that he rarely used... it has some modchip inside that I believe it's a crappy clone:



any idea what it is?

TIA for any info!

 

found it here after searching google images: http://chip.tut.su/=ps2/ps2mods_user_boot.htm
it appears to be a messiah 2.xx (clone of it?) ... are they any good?

edit: found diagram as well: http://www.picsystems.net/diagrams_ps2/messiah2/messiah1.33b_v10.jpg

I just realized this thread became pointless
