I suppose if Amiga experts like you guys here know nothing about these documents, I suppose they never existed. It reminds me the policy Apple had about its Macintosh machines; the first models up to the Plus were well documented, both from a hardware and software point of view. But if you try to get info on later models...good luck.
I think Commodore introduced this policy as they did not want people to access hardware directly and use only OS provided interfaces (likely same reason for the Mac).
