Spectrum +2 Machine Language For The Absolute Beginner
======================================================

The Book
--------
The Spectrum +2 is a machine long dreamt of by home computer users - 128K of memory, enhanced sound, built-in data recorder and joystick port, and much more. And here, in Spectrum +2 Machine Language For The Absolute Beginner, is the book which shows you how to utilise to the full the +2's extraordinary potential.

From the introductory chapters, which lay down the first principles of machine code and its differences to and advantages over BASIC, Joe Pritchard conducts you through a comprehensive course in Z80 programming. Registers, addressing modes, eight and 16-bit operation, jumps, loops and interrupts, keyboard reading, screen handling and graphics are dealt with in turn. The course concludes with some useful ROM routines and appendices for quick reference.

Those already fluent in machine language will also find much that is relevant, as Joe Pritchard examines those features of the Spectrum +2 unfamiliar to even experienced Sinclair users. For instance, the chapter on Sound is alone a most worthwhile addition to any programmer's library.

Spectrum +2 Machine Language For The Absolute Beginner - the perfect companion to a powerful new computer.
