so my model number is SCPH-39010/N
and i had the little screw in the hdd tray.
i looked on the interent and found a few guides but they were giving me mixed messages..
one said if i have that one small screw, i have a v5/6 ps2.
another said i could have a v5/6 or v7 ps2.
that really doesn't narrow it down very much for me.
i'm goign to be installing a duo2se.
thnx in advance for you help,
