I'm a first time poster...

I have a 15" G4 1.5 (A1095) with a dead logic board. I have found a few replacement boards on ebay, but the all have 64 VRAM cards as opposed to the 128 card on my current (dead) logic board. Does any one know if it possible to upgrade/retrofit the 1.67GHZ Logic board to my current machine? Most of them have the 128
VRAM cards.

Thanks in advance,
