     	 25 years of coding experience in assembler on the Amiga by

			     ---> dissident <---

After coding the Amiga for 25 years in assembler, I decided to collect
all my tips & tricks of this decade and to provide the Amiga publicity
my knowledge. I found out some things on my own, some things by analyzing
the code of demos and I read about some topics in a forum or in Amiga
magazines. Not to forget the hints of many persons, which I included as
mentioned.

For the second edition I've revised this guide completely, did many
corrections and added new experiences I've made since the last release.

I want to provide you a bound of different topics covering the peculiarities
of the amiga hardware and music software like the Protracker. Feel free
to browse through the paragraphs. I wish you lots of fun. :)

This document deals with the following topics:

-Peculiarities of the MC68020/60
-Peculiarities of the chipsets OCS & AGA
-Optimizing&tricks on the MC68000/20/60
-Optimizing&tricks on the chipsets OCS & AGA
-OCS/ECS/AGA and its differences
-Coding on the OCS with upward compability
-Programming the CIA on MC68020 or better machines
-Hardware bugs and their software solution
-Tricks using the Protracker and its replay routine

and many more interesting stuff.
