What Ver is my PS2??
 

Heres the Info:
Model: SCPH - 30001 R
Serial: U0xxxxxx
Date Code: 1c
NTSC
Barcode:PT2xxxxxxx7

There is no 3rd screw in the drive bay but there is the "R" depicting a v5...what version is my PS2???? I have read on another site that some V5 PS2's were shipped with V4 boards....is this what i have here????
Any help would be appreciated....
Thanks!

This could run forever. The one thing nobody has checked or been asked for is the Driver Version from the Configuration option in the Browser. So, I'll put out a call.

Remove the expansion bay cover, the screws are located on the top, along the edge of the bay area, if you have 2 screws it's a v4, 3 its a v5

it is version 5, i have the same one.

My PS2 30001R is the same except it has a U11xxxxx SN. It has 8 screws in the bottom, Playstation Driver 1.10, and the expansion bay has 2 small gold screws on the top in the front at the edge which hold the connector in. Is this V4 or V5? I keep getting conflicting info. Can someone who knows for sure please let me know?

the software version is 1.10.....it has the 2 screws in the expantion bay....i am also getting conflicting oppinions...I am leaning towards V4 myself...

Did you guy's not read my post above?? Two screws = a v4! Three screws = a v5!

Ok then, with the v4 does the swap trick work with just a GS2 and no modchip? If so what ver of GS2 is needed? Also, I've heard about the mod to install a switch to open the tray for swapping. Does anyone have the schematic? I just don't think I want to mess with soldering all those tight spaces for the modchip.

If you are willing to take apart the PS2 and wire up a tray switch you may as well install a chip. Anyway swap trick methods are at www.ps2ownz.com.
