Apple Macintosh series tech info
This is a brief breakdown of the major components in every 680x0 and PowerPC-based Macintosh computer. In most cases the information is sourced directly from Apple's own public hardware developer notes that they used to release with each new Macintosh. This corrects a number of errors in my now very old previous version of this listing, and continues with NewWorld machines to show the continuity in hardware design. (Last revised December 18, 2024)
Note: I don't 100% guarantee accuracy here, especially for G4/G5 machines. Also, some machines had a lot of codenames. I've tried to use the one that was most commonly used internal to Apple, but information on that is obviously hard to come by, especially for post-1993 machines. And it got worse for post-Steve Jobs 2.0 machines, which mostly had boring letter/number codenames.
Systems were originally listed in a simple sort order by name but I've been changing over to release date order (and I may add the release date as a field).
We're separating the old single-page design into multiple new ones, and adding a few.
