I really am fond of the DE RE Atari and Mapping the Atari copies which are on the internet.
i would have achieved much more when I had had the DE Re Atari book back in the day. Really.
However, i welcome you in the year 2010. We have web 2.0 and are slowly going to web 3.11
So forget about about the books and lets do a wiki. Really.
For once, i am not afraid of writing some pages of technical text. Its just that everyone can add soem bits if someone starts a Wikipage, but it would be harder to edit a whole book.
If someone starts a Wiki (well, if there isn't already one) i am with you and try to contribute the parts I have knowledge and experience of.
But I can assure you, i would never say f.e.: "I can write a chapter about ANTIC all of my own". Purely, because I haven't tried everything i could have tried.
