The Book

This step-by-step text introduces the complete beginner to Z80 programming in the well proven style that has been described by the critics as “worth its weight in gold“. No prior knowledge is assumed and the aim throughout the book is to ensure that the beginner realty succeeds. By the end of the book every Z80 dass of instruction has been explained in detail. Numerous examples illustrate the points while exercises (along with solutions) test the understanding. Later chapters show how additional commands may be added to BASIC including, for example, a circle drawing routine.
