"Indeed, into the 1980s, computers often came with schematic diagrams of their circuit boards. The Apple II, for example, shipped with a reference manual that included a full schematic of the computer’s main board... Modern user manuals lack such depth. The most complex diagram in a recent Mac Pro user manual instructs the purchaser on how to sit at the computer"

Unless you buy OSHW, which comes with full schematics (at least, of the open parts :( ), but it's not something you are likely to find in $RANDOM_CONSUMER_STORE.
