Mastered the basics of your ZX81?
Want to go further?
This follow-up to PEEK, POKE, BYTE & RAM! covers these major areas:
Data structures - for efficient processing.
Structured programming - for programs that work.
Machine code - for high-speed action.
Appendices - to help you program in machine code.
Starting with a simplified, imaginary machine to explain the ideas behind machine code, the authors take you gradually to the stage of tackling the complexities of the Z80 microchip itself.
The majority of the book is machine independent for owners of Z80-based computers such as Research Machines 380Z, Tandy TRS80, Sharp MZ80K and MZ80B, the Sinclair ZX80 and the ZX Spectrum. But all programs can be run without adaptation on the Sinclair ZX81 with a 16K RAM pack.
Included are detailed case-histories of program design, with examples of a library cataloguing system, supermarket checkout simulation, text-editing and word-processing, and an educational program (by Eric Deeson) to test your knowledge of French, plus a variety of useful machine code listings.
