Spectrum Machine Language for the Absolute Beginner: 2 (Retro Reproductions) Hardcover – Illustrated, 4 May 2020

The book is fanastic. Very readable style and good detail and explanation. Not far in and I can start to understand how CPU z80 is works. For example, I was too lazy to recall or understand HEX representation of binary or decimal. Now it's obvious how it relates to bits in context of an 8bit process. Nice cover and well bound even if the print quality seems a bit low budget. Would recommend even if it's a subject you are only vaguely interested in.

If you're after a fairly easy to follow introduction to assembly for the Spectrum then you could do worse than this.It's a faithful reproduction of the original book and presents good value for money given that original runs of books on assembly seem to go for a premium now.

This version of Spectrum Machine Language for the absolute beginner is a lovely book and is perfectly sized. The pages are slightly cream in colour (nice touch) and are of good quality. It feels really nice to hold and I thoroughly recommend getting a copy, especially if you fancy learning 8-bit machine code from one of the best introduction to 8-bit machine code programming books ever written!

This is a great book if you're interested in getting started with z80 assembly coding on the original ZX Spectrum or the ZX Spectrum Next. Machine language is stated in the title but this is really about assembly language: the human readable form of the 0s and 1s that comprise machine language (also called machine code). The author does explain the difference and provides the background so that the reader can make the distinction.It is an exact reproduction so the font, the writing style, etc. are as per the original from the 1980s. Consequently there a few typos from the original that are also authentically reproduced, but this doesn't detract from the usefulness of this book.

Treat myself to this book after getting hold of a ZX Spectrum Next and thought I'd at last delve into the black art of machine code programming, having given it a wide berth for the last 40 years!Despite the topic, the author approaches it in manner easy to understand for the beginner. This is a nice change from books that say you don't need a prior knowledge but then find you do. The explanation of how computers count is really clear and interesting and gives a good understanding of hexadecimal and why its used.The book isn't without issues though!! There are errors through it that really should have been picked up in proof reading. For example the first program (in BASIC) you're asked to type in simply does not work, and its clear from looking at the code that it would never have worked. This is really disappointing, but if you persevere and take the time to work out what is wrong with it then you'll actually learn a lot more than just by reading. This might not be for a lot of people though as longer code, especially when you get into the assembly detail, can be very difficult and frustrating to unpick.In general though I think this is a good book. Even if you don't intend to follow through the examples, you'll learn a lot about the simplicity (and complexity!) of the Z80A and how it works.

A good reference book with some questionable grammar and spelling at times and the typeface is very 1980s. Really good retro book covering the subject of z80 machine language for those who were maybe too young to look at learning it back in the day.

I was not the brightest when it came to Mathematics but this Book explained the Binary system very lucidly and made it easy to understand.This Book enabled me to understand machine code and fall in love with Programming. It also spurred me on to obtain a Degree in Computer Science in 1991 and earn a very good income.This Book basically set me up for life and allowed me to retire at 39.In other words, the best Book I ever read.

The content of the book itself is ok I suppose but there are two faults which are quite a big deal.Firstly the writing style might have been fine when the target audience was a bunch of kids who’d never so much as touched a computer before but now most of us have been using them for many years, a lot of us with prior coding experience, referring to registers continually throughout the book as fingers and toes is just outright confusing. You have to continually ask yourself what on earth they’re going on about. Use the analogy to start with but then drop it and use the proper terms.So onto the lazy reprint bit. This strikes me as just a money grab. It really would not have hurt for the people that reprinted it to have actually proof read it. Good luck getting the code examples and programs to actually work should you go to the effort of typing them in!! There’s errors all over the place!
