right here goes - the ps1 uses something crazy like 7.5 v as said earlier, so the adaptor is easy, as sony make one. for the ps2 you need a power invertor that shifts 12v to 240v, i work for ripspeed and we sell the kits for ps2s for £75, that has the power leads and the a/v leads with it all you need then is a screen, you can pick them up anywhere from £100 to £3000 depending on what you are after. if you go to your local halfords and have a look in the audio customer catalog you can see all the kits that we do, and we price match, and fit too!!!
