which version is my ps2. I bought it the first day that it came out in the USA.

1. Look at the underneath of the console. Do you see this symbol ?

2. Take off the expansion bay cover and look inside. Do you see this screw ?

If none of these Items are visible then you have a Version 3

If Item 1 is visible but not Item 2 then you have a Version 4

If Both Items 1 and 2 are visible then you have a Version 5
