How can you tell...
 

What version your PS2 is?:confused:

Tell me how many screws are on the bottom 8 or 10
next what is the model # and the date code??

There have been lots (and lots) of threads about identifying PS2 models (both PAL and NTSC). Try using the search facility on this forum, using something like "version". Charlie_ps2 posted a list recently for NTSC versions, and most probably posted something about PAL versions too.
