Do you have the Slim-Line PlayStation2 model or original PlayStation2?

• If you have the original model, you will need to buy a Network Adapter for your console (eBay).
  
• If you have a Slimline PS2, the Modem is inbuilt in the console, HOWEVER you will need to contact Sony Computer Entertainment Europe Customer Services (See your instruction manual!) as they will need to send you a registry disk so you can access your modem and take your games online - You will not be able to play online without the disk, so be warned!
