As seminal books of the early computer era, Beneath Apple DOS and Beneath Apple
ProDOS showed Apple II users how their operating system was put together and how to
exploit it for their own purposes. They were must-have books for programmers and
those who were just curious about how their computer's operating system worked. This
is an amalgam of the two books, cleaned up and re-typeset.
