The Guru Book
I've actually got this book in .PDF format from a torrent, quite a while back.
I thought at the time when I'd seen it, it was a reference guide to all
the Amiga's Software Failure Guru Numbers. Wasn't even aware of this project.
I downloaded it because being an ex-680xx coder, it was one of those things at the time, that were invaluable! I did used to have an in-depth copy of all the guru codes from an Amiga magazine.
As I collect and archive old Amiga related material, in the moment of excitement, I naturally saved a copy to my old Amiga Realm Project folder.
But since reading through the book, its not what I'd thought it would be anyways.
