Machine code

Machine code or machine language is a system of instructions and data directly understandable by a computer's central processing unit. Contents * 1 Machine code instructions * 2 Programs * 3 Assembly languages * 4 Example * 5 Are machine languages special? * 6 Relationship to microcode * 7 See also * 8 Further reading

Machine Language For Beginners

This book is designed to teach machine language to those who have a working knowledge of BASIC. For example, Chapter 9 is a list of BASIC statements. Following each is a machine language routine which accomplishes the same task. In this way, if you know what you want to do in BASIC, you can find out how to do it in machine language

The Second Book Of Machine Language

This book shows how to put together a large machine language program. All of the fundamentals were covered in my first book, Machine Language for Beginners. What remains is to put the rules to use by constructing a working program, to take the theory into the field and show how machine language is done

Introducing Assembly Language

tart programming immediately in machine language! Turn on your Atari computer and type in this program. Then run it, type a few words, and you'll see something very interesting on your computer screen.

A Guide to Effective Programming

The internal layout of the ATARI 400/800Tm Computer is very different from other systems. It of course has a microprocessor (a 6502), RAM, ROM, and a (PIA). However, it also has three special- purpose (LSI) chips known as ANTIC, CTIA, and POKEY. These chips were designed by Atari engineers primarily to take much of the burden of housekeeping off of the 6502, thereby freeing the 6502 to concentrate on computations. While they were at it, they designed a great deal of power into these chips. Each of these chips is almost as big (in terms of silicon area) as a 6502, so the three of them together provide a tremendous amount of power. Mastering the ATARI 400/800 Computers is primarily a matter of mastering these three chips.

The Master Memory Map for the Atari

Here at Educational Software we get tired of computer terminology. However, many of these words are becoming a part of our language. As we explain the inner workings of the Atari, we will have to refer to some of the following words. If your find some term we forgot to mention here, it's probably because it is fully explained in the appendices or at the memory location it pertains to. You should also read your BASIC manual in order to understand the terms that have to do with the BASIC language

Mapping The Atari - Revised Edition

The comprehensive sourcebook and memory guide For beginning and veteran programmers of the Atari 400, 800, XL, and XE personal computers.

Compute!'s First Book of Atari Graphics

This special addition to our First Book Series represents the first time we've published a theme-specific book. COMPUTE!'s First Book of Atari Graphicscontains published as well as original, unpublished material that has been carefully chosen to provide any Atari user with helpful, useful information on the extensive capabilities available with Atari graphics.

Atari Player-Missile Graphics in BASIC

Surprise! Atari has a secret feature that sets it apart from most other personal computers. It's called Player-Missile Graphics (PMG for short). With PMG you can create all sorts of special graphic effects--effects that would be extremely difficult, if not impossible, with an Apple, IBM, or TRS-80.
