Ford and Topps work is well structured,organised and clear. For
students and professional engineers wishing to master Motorola's
68000 and its siblings' assembly language this is an excellent text. The sections abound with examples and in pointing out how the orthogonal architecture of this processor and its rich addressing modes ease I/O programming as also for data structures.. linked lists, decision trees and so forth. The weakness if any is in the programming of the more sophisticated the second generation interface graphic, memory management chips which work in the asynchronous mode as also some discussion on the assembler vs high level block structured languages like C or C++. I hope to see this corrected in future editions.
