    Jolyon's 2003 HTML version Introduction:
    HowToCode is now well over 11 years old, and has not been updated for nearly ten years. I thought it would be a good idea to make a version available on the web, so here it is. For those of you who never figured it out, Comrade J was my alias - I wrote demos under that name, while continuing with a 'respectable' career as an Amiga developer with my family company, Almathera Systems Ltd. When this file was written, many of the secrets of the then-jealously guarded AA chipset were revealed to demo programmers for the first time. I know (because they told me) that many of the major demo crews who produced such fantastic productions for the Amiga 1200 did so with the aid of these documents. Far from being upset with the release of AA information to developers, I think that many in Commodore were secretly relieved that this information was being more widely spread - indeed I had engineers from CBM in the US contributing by email to this archive (at least one of whom remains anonymous today, and don't ask me to tell because I've forgotten his name!)

    Please note that this file is the work of many authors, although the spelling mistakes are all my fault!

    I apologise in advance for mistakes in HowToCode, I am unable to check everything thoroughly and certainly not on all machines, and in particular with AGA information so much misleading and contradictory information is going around that it is inevitable that mistakes will happen. Please point these out to me, however trivial! I promise I won't be angry if 100 people point out the same mistake. If no one does and everyone tells me later that they knew - then I will!
