Yeah..... Don't take this the wrong way BUT:
1st thing to do: Throw the Neo chip away....
2nd thing to do: Buy a Magic 2....
3rd thing to do: Ship your PS2 to Bill @
Freedomlives.com and let him do the install...
Seriously, if you are concerned about the soldering part of the install, you should NOT even attempt it... Let someone that knows how do it.....
