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 July 31, 2023)
We're separating the old single-page design into multiple new ones, and adding a few.
