Is there a guide to part numbers, classes, and components?
Hi! I've been dealing with lots of A1181s lately, and I tend to go by the part numbers of the logic boards, because that is a fairly absolute and unmistakable way to reference a board, however it seems there is not a good way to cross-reference the board numbers with the early/mid/late year designations, or the classes of machines(Penryn, Santa Rosa, etc.), or to know definitively which of them has which variation heatsync (3-wall or 4-wall connectors, straight or curved), or which battery connector (Energy Star vs non-Energy Star). Some people will go by "mid 2008", others with say "Santa Rosa", and another might reference a board number, but beyond vague references to these things I don't think most people really comprehend what any of it means, which is not surprising because it's not like Apple makes it at all obvious.
Does anyone know of a comprehensive and reliable index which cross-references all these confusing terms and parts? I've found a few, but they are generally incomplete and filled with errors, and I need something I can depend on when telling any given person that a board will/won't work in a machine. It's almost as if Apple is intentionally confusing the issue, and on the back-end they probably have a system that they aren't letting the rest of us see.
Is this a good question?
