Where can I get highly technical documentation of Macintosh hardware? I am often looking to dig deeper than the overview technical specifications that Apple provides and miss the old Developer Notes that used to be published as Apple Hardware Documentation in HTML and PDF form.


2004 ADC - Developer Connection - Hardware Reference Library


I can't locate any of these MacBook Pro or Air / Mac Pro developer notes past early 2008 or so in the archive. Using a google search as well as searching for developer note is yielding no hits. I can't tell if guides like this are no longer produced or are just hidden behind a pay wall. What programs or resources provide level diagrams and internal hardware design documents short of getting a job with Apple? I'm willing to pay for them, just looking for sources of this information.

I'm not necessarily looking for repair manuals since iFixit.com does a nice job of documenting tear down disassembly of pretty much anything Apple makes. I'm more interested in the technical discussion about bus speeds, design tradeoffs, and hints on how the machines are built and where the specific limiting factors lie.

For example, being able to read about the storage bus of the MacBook Air lets me know if I can replace the flash storage and not guess whether it's on a SATA bus or uses a proprietary controller in addition to a proprietary shape / connector.
As far as repair of hardware http://ifixit.com is actually pretty awesome, more visual than you may be looking for however.
