version of ps2?

looks like you got a V5/V6 board. They shared the same boards. This is what I have been informed of anyway,
The model numbers can be SCPH-30000R, SCPH-30001 R, SCPH-30002 R, SCPH-30003 R, SCPH-30004 R, SCPH-30006 R
But also some SCPH-30000, SCPH-30001, SCPH-30002, SCPH-30003 and SCPH-30004 PS2 have a V5/V6 main board.
From what I have read, this is a pretty good platform for any mod...anything pre-V4 you really didn't want to mess with.
