For really fast-running programs, as required for games, moving graphics and word processing, your program needs to be in assembly language which runs much faster than BASIC. Unfortunately, the Sinclair ZX81 does not allow you to enter assembly language programs directly, so while you can write assembly language programs for it, they have to be translated into machine code before they will run on the machine.

Tim Hartnell's first book became a best-seller because it helped the newcomer to computing to explore his or her ZX80 and make the most effective use of it.

In this book GETTING ACQUAINTED WITH YOUR ZX81 Tim does the same for the owner of a ZX81 (or new ROM ZX80). Whether you've never touched a computer before the ZX81, or you've had a lot of experience, you'll find much of value and interest in this small volume.

This book by Mike Lord is not intended as a beginners guide to BASIC. Neither is it an introduction to the ZX81. Instead it carries the reader on from where the ZX81 BASIC Manual leaves off; by giving the reader a variety of programs to run, and - more importantly - a wealth of detailed information about the computer and how to get the best out of it. Whether your interests lie in games programs, in the business or engineering applications of the ZX81, or even in attacking it with a soldering iron, you should find something of interest and value in these pages.

The ZX81, equipped with its 16K RAM pack, has at least as much storage as most other microcomputers. It uses the same Z80A CPU that is featured in many of the best microcomputer systems and which, in other machines, can run wages, stock control and word processor systems. So why not in the ZX81?
The aim of this book is to push the ZX81 a long way in the direction of 'serious' applications, but without the use of machine code. All the programming is easy to follow and fully explained, so that the reader learns, a step at a time, how complex programs are constructed and written.

But these programs are just a beginning. Discard the belief that the ZX81 is too small for real computing work, and use the flexible techniques described here to fill your own special data processing needs.
