# A Practical Guide to Machine Language Programming on the Timex/Sinclair

Using only 16 chapters and 8 appendices, the author takes you on a guided tour of the Z80 in Sinclair country, distinguishing the CPU properties from the system behavior with clarity and flair. Your tour guide is an expert whose practical experience includes writing the word processor “WORD*” on which this book is written. Appendix 4 contains the assembler, written in BASIC, for you to type in and use to try routines.
