Books

Here's a list of books that relate to the 680x0 family, both interfacing and programming:

Microprocessor Systems Design. 68000 Hardware, Software and Interfacing, 2nd edition, Alan Clememnts. Pub. PWS-Kent 1992. 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.

M68000 8-/16/32-Bit Microprocessors Programmers Reference Manual, Fifth edition, Motorola. Pub. Prentice-Hall 1986.

Programming the M68000, 2nd edition, Tim King and Brian Knight. Pub. The Benjamin Cummings Publishing Company Inc. 1986.

Microcomputer Architecture and Programming. The 68000 Family, First edition, John F. Wakerly. Pub Wiley, 1989.

An Introduction to Microcomputer Systems, Architechture and Interfacing, John Fulcher. Pub. Addison Wesley, 1989. Lots of theory. Covers multiple CPU families, including 68000, up to the 68030.
