Artificial Intelligence on the Commodore 64 shows you how to implement AI routines on your home micro and turn it into an intelligent machine which can hold a conversation with you, give you rational advice, learnn from you (and teach you) and even write programs for you.

The book explains AI from first principles and assumes no previous knowledge of the subject. All the important aspects of AI are covered and are fully illustrated with example programs.
For many years science fiction books and films have contained 'intelligent' computers which appear to be at least the equal of man. Although some of the features described in these remain illusions, extensive research into AI has brought may of the ideas much nearer reality.

If you're tired of ordinary computer games . . . if you're looking for something exciting and different to do with your C-64 .. . here's the answer! It's a whole collection of artificial intelligence (Al) projects designed to tap your micros real problem-solving capabilities for both practical and entertainment applications.

Leading off with a definition of artificial intelligence and an overview of Al concepts, the author provides 16 ready-to-run programs in BASIC to illustrate your micro's cognitive powers. You'll cover tree searches (testing all possible solutions to a problem), hueristics (a modified trial-and-error technique), algorithms, and pattern searching/recognition routines.

You'll find out how to solve simple—and not-so-simple—puzzles like Towers of Hanoi and the Knight's Tour of the Chessboard . . . explore concepts of animal behavior and how it can be simulated . . . analyze how natural language can be recognized and acted on by the computer . . . simulate an actual human-machine conversation . . . and use an interactive routine that allows your micro to make deductions through clever application of set theory. There's even a program that allows your micro to write its own program modifications!

And, as an extra bonus, the author has included a functioning word processing program (which he used to write this book’s manuscript) and a graphics program that lets you draw on the screen with a joystick.

Totally fascinating and packed with techniques that will help you improve all your BASIC programming practice, this is a sourcebook that will open a whole new dimension in your computer usage!

Commodore 64 Whole Memory Guide is much more than a memory map. Instead of just giving memory locations it gives you a detailed description of each location, explaining what it's for, how it is used by the computer, and, more importantly, how it can be used by the programmer.

Utilities to take the pain out of programming .. . Utilities to customise your 64 and explore its hidden potential .. . All Commodore 64 programmers will find this software toolkit of programming aids, BASIC enhancements and , other utilities truly invaluable.

Mapping the Commodore 64 is a detailed and comprehensive explanation of the Commodore 64 computer's memory. Although some parts of this information have been published before, this is the definitive work—complete and clear discussions of all the important user-alterable memory locations in the computer, as well as details of the BASIC and operating routines in permanent ROM memory. Whether you're programming in BASIC or in machine language, you'll find this sourcebook invaluable.

Serving both as an introduction to 64 architecture and memory use, as well as an excellent resource to help you tap the computer's powerful, but hidden, features, Mapping the Commodore 64 includes:

• An explanation of all Kernal and BASIC routines.
• Demonstration programs for many of the operating routines.
• How to turn individual bits on and off.
• Details of how to create and use sprites in your programs.
• How to create the precise sound effects you want.
• How to create your own characters and where to safely store them.
• A program that allows single keystroke entry of BASIC keywords.

If you're familiar with BASIC, you'll turn to this book again and again for instruction, advice, and clarification. If you're already programming in machine language, you'll find this book an indispensable guide to memory locations and routines. But no matter what your programming experience, once you've used Mapping the Commodore 64, you'll wonder how you ever got along without it.

Mapping the Commodore 64 and 64C is a detailed and comprehensive explanation of the Commodore 64 and 64C computers’ memory.

'Back in the days' so called 'illegal' opcodes were researched independently by different parties, and detail knowledge about them was considered 'black magic' for many conventional programmers. They first appeared in the context of copy protection schemes, so keeping the knowledge secret was crucial.

When some time later some of these opcodes were documented by various book authors and magazines, a lot of misinformation was spread and a number of weird myths were born. It took another few years until some brave souls started to systematically investigate each and every opcode, and until the mid 90s that Wolfgang Lorenz came up with his test suite that finally contained elaborated test programs for them.

Still, a few opcodes were considered witchcraft for a while (the so called 'unstable' ones), until other people finally de-capped an actual CPU and solved the remaining riddles.

This document tries to present the current state of the art in a readable form, and is in large parts the result of pasting existing documents together and editing them

To understand the workings of the Commodore 64 (henceforth shortened to the C64), the user needs a solid understanding of C64BASIC. This Guide gives the essential knowledge necessary for that understanding.

This book was written with the beginning or intermediate programmer in mind.  You do need a general understanding of how your computer operates, and how to write simple programs in BASIC.

The BRAIN is a clearly written detailed explanation of the Commodore 64 computer's memory. If you are a begginer here is the information you have been hunting far. Advanced programmers will use this booklet again and again as a powerful tool. THE BRAIN is a no-nonsense approach to a guided tour of the most extensive memory map on the market to date.

• Written in dictionary format
• Easy to understand terms
• Extensive sound & graphic sections
• Understand existing programs
• Identify program storage locations
• The kernal at your finger tips
• Addresses in hex and decimal
• OPS code help chart

The programmable logic array (PLA) in the Commodore 64 (C64) is used to create chip select signals from various other signals, e.g., from the current address. These signals control which chip is to be connected to the data bus. Therefore the PLA is responsible to implement the memory map of the C64.

If the PLA is broken, the CPU and the VIC-II1 direct memory access (DMA) can not access the right memory and I/O devices anymore. In this case some chips can not be selected or more than one chip is active at the same time. A total or partial malfunction of the computer is the result. If a PLA is replaced with a part which does not meet certain timing or electrical constraints of the chips connected to it, the computer becomes unstable, possibly depending on temperature or hardware extensions used or may refuse to work at all.

A knowledge of the Commodore 64 kernal software and the hardware with which it interacts is essential for programmers wishing to make full use of the machine's capabilities. The kernal software provides the interface between the user, the BASIC interpreter and the electronics - and a thorough knowledge of its functioning gives the programmer a wealth of ideas and methods for interesting programming techniques.

This book gives the programmer a unique insight into the operation of the Commodore 64 plus a wide variety of very useful hints on subjects as diverse as reconfiguring the keyboard and anti tape-copying security. The book also covers the user port and the addition of external circuitry to it.

There is now a wide variety of books available for the CBM home computers, but few of them really get stuck into the practical problems that afflict any programmer once he is past the beginner stage. This book can't do the work for you, but it can help you get things working inseveral ways.

Right at the start when you begin to use your machine with the help of your manual, you will often find an explanation difficult to follow. Reference to this book may help by giving another way of looking at things.
