Hi all! So happy to have found this community.

I'm looking for a schematic or a board view of the logic board used by the "Late 2005" Apple Power Mac G5 Quad-core or Dual-core.

Since the schematics seem very hard to find, I'm specifically interested in Apple's "U4 (Kodiak)" implementation of the IBM CPC945 northbridge, and particularly how Apple wired the memory controller pins.

There's tons of misinformation about this chip online, and I'd be...
