PS2 HDD network adapter issue

[wafcjr]

My little brother took apart my adapter (ethernet/modem). and i could only find the ps2 connecter piece to it. I was wondering if i could get some pinouts for the adapter so i could solder the HDD directly to it. (dont kare about online play). Or i would be willing to purchase another one for $15 USD. TY for the help.
