The Jaguar Underground Documentation

This is an attempt to document the internals of the Jaguar, Ataris highly successful 64 bit videogame console. This documentation is created independent of Atari and provided to you for educational purposes only. What you're seeing is a snapshot of the draft writing of the documentation. It is released now, because now is the time it is needed, not because it is in a form that merits release.
You're very much welcome to join in the effort. If you find anything that is missing or described incorrectly, please by all means let us know. If you prefer to remain anoymous, that's OK.

Updated versions of these documents are spread via the "Atari Jaguar Hackers' Underground Mailing List". The documentation proper isn't HTMLized yet. This will be possible when the results and the contents start to stabilize.

We can not emphasize enough that these docs contain MANY inaccuracies. We are constantly finding embarrasing bugs, because we made stupid assumptions and/or didn't test carefully enough. If something isn't working as expected try an experiment on your own. And then tell us about it!

Nevertheless we hope that these files will prove to be helpful in your explorations. Good luck.
