newbie question

[bigorangekitty]

i'm sure people ask this question a lot, so i tried searching the ps2 forum to make some sense...after all, i am a newbie ... anyhow, i can NOT find which version PS2 i have, or which mod chip i should get and was hoping the nice people on this forum could possibly help? i don't see any screws, the expansion port slides out, and the version info its displays is: scph 30001, browser 1.10, cd 1.10, PS Drive 1.10, DVD 1.10U ...could someone please help a newbie! thank you!
