It's well documented; the circuit diagrams are
readily available, the
service manual is reasonably easy to find, and includes circuit
description, upgrade instructions, schematics, board layouts,
mechanical drawings, etc. And other documents cover the systems calls
in detail, how to build interfaces to the bus, how to write ROM
software for it, and so on.
The original Apple ][ reference manual wasn't nearly as comprehensive but
still it included the schematics, ROM listings, and other tidbits of
useful info for understanding all the various subsystems of the basic
Apple ][. It was my "bible" throughout high school (how deliciously
nerdy, eh? :)
