I really like this book. I find the descriptions clear and easy to understand. Without this book, it would have been much harder to get my head round the 68681 Duart, as all the datasheets I've seen from the various manufacturers are very badly written.
Not much to say really about this. It's the book I refer to whenever I need full details of a given 680x0 instruction. Unfortunately, it only covers 68000, 68008, 68010 and 68012. I keep looking for one that includes details of the later processors.

An okay book that takes you through all aspects of programming devices up to and including the 68020.
