That size difference looks consistent with what I scaled off some other photos of the apple port.

Sorry to revive such an old thread, but I recently aquired an AIW 2006 PCIe Edition (european version) without the surrounding paper box, but with everything else included. Only the manual bag was opened while the rest was still factory sealed. For less than 10 bucks definately a purchase I couldn't let pass by ...

So I can say that there is another version of the silver stab connector (ATI:6110020800G WSTG:GC219RM-109 Rev. A). Might have the same function and be just a revision of the 6110020700G, though.
I'll attach a photo of the cable set and the driver disc below.

If there is interest to get an image of the driver disc, just contact me.

That silver stab connector for the X800XL is absolutely impossible to find anywhere! Could you upload the driver disk please? Does anyone know the part number for the US version of that splitter cable and does anyone have it for sale?
