This appendix was written primarily for hardware engineers interested in
designing Plug-In Cards for the Zorro III expansion bus.  While it may
occasionally be of use to software engineers interfacing to such Zorro III
PICs, Amiga system software provides an interface layer
(expansion.library in the Amiga OS) which manages the needs of most
card-level software. A reasonable level of microcomputer knowledge is
prerequisite to get much meaning out of these pages.  A good understanding
of the Motorola 680x0 processors will be quite useful, as will be an
understanding of the Zorro II expansion bus used on earlier Amiga
computers such as the Amiga 2000.
