COMPUTE's 128 Programmer's Guide is a book you'll want at your side whenever you're programming or using the Commodore 128. It's not intended to replace the 128 System Guide. In stead, it's a source of additional ideas, programming advice, and technical information. It covers the 128 in all of its several modes, and every explanation is written in the clear, easy to- read style that's the hallmark of COMPUTE! publications.

SYSRES is an operating system which works in conjunction with the BASIC operating system in your Commodore-64 to give you, the programmer, advanced program and file manipulation ability. The syntax has been carefully selected to be as similar as possible to many other such systems, while adding a host of additional features. SYSRES'" is designed to be addictive to programmers but NOT addictive to programs. This means that no commands are added or changed in the way in which they behave within a program. Software developed under SYSRES is fully compatible with a non-SYSRES environment. By using an extremely powerful syntax structure, SYSRES adds over 1100 new functions to BASIC, while only using 33 new command words (plus 11 dos-support commands). Even with all of this power, SYSRES is very simple to use, because most commands accept syntax with which you may already be familiar, the more powerful features are optional. SYSRES hides away under BASIC, so it USES NO RAM which would normally be available to BASIC programs (except 256 bytes from $COOO to $CFFF for BASIC interface)(Ref: pp. 2-3). One reason SYSRES is not in a cartridge is that a cartridge takes 8K away from your BASIC RAM!

THE COMPLETE HANDBOOK FOR COMMODORE TELECOMMUNICATIONS The newest and most exciting chapter of home computer capabilities is now unfolding. Today the ability to hook your computer up with your phone to tap a vast storehouse of information and employ a tremendous array of services has expanded the uses of your Commodore' 64™, SX64™, and VIC 20™ far beyond anything previously possible. This is the one book that gives every Commodore owner all the knowledge needed to take full advantage of this new dimension in computer use. 

Commodore computers are versatile machines that represent a landmark in the era of personal computers. The use of large-scale integrated (LSI) circuits in these computers enabled millions of people to purchase Commodore computers as their first home computer. The purpose of this book is to show you how to build electronic projects that will enhance your computer. But more than this, the information can provide a foundation upon which you can build. Perhaps this book will provide the spark to ignite your own creativity. Many projects lie on the frontiers of technology. The projects represent a starting point for the basic tools with which you can explore on your own, and perhaps make a contribution to emerging technologies. 

How do you interface a home·made joystick, stepper motor or a fully fledged robot to your Commodore computer? How do you write software for stepper motor control and how can you use the software and a few penny worth of components to get an output for analogue control? Step by step instructions guide you in constructing a wealth of gadgetry.At the same time you will build an understanding of the principles of digital and analogue input and output. 

Here is a good selection of practical, task-oriented programs for those who understand the analytical potential of the personal computer. Forty-two programs on amateur radio and electronics make this a valuable and time-saving tool. The programs have been tested, and all work as presented on both the Commodore 64 and the Commodore 128 in 64 mode. Along with the programs the author provides: 
• useful equations such as capacitance, impedance, inductance, length, and reactance 
• diagrams such as parabolic dish, voltage regulator, LC tuned tank circuit, instrumentation amplifier. monostable & a stable circuit, triangle waveform oscillator, and operational amplifier 
• sample runs for many programs 
A final section shows how to import a BASIC program from any computer with a 300 baud RS·232C serial port to either a Commodore 64 or Commodore 128 computer. Amateur rodio hobbyists, engineers, serious programmers, and technicians alike will find this baok a useful addition to their computer library. 

Discover a whole new dimension in your C-64's programming abilities! 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 (AI) projects designed to tap your micro's real problem-solving capabilities for both practical and entertainment applications. Leading off with a definition of artificial intelligence and an overview of AI 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 Tourof 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! Timothy J. O'Malley is a writer and programmer whose experience spans both mainframe and microcomputer experiments in artificial intelligence. 

Soon after purchasing your VIC-20 or Commodore 64, you undoubtedly discovered that home computers are sophisticated and powerful tools. But YOl !'Ve also found that, by itself, the computer is not enough. With nothing but a computer, how can you use software on tape or disk? How can you print out a copy of a program listing or even a letter? How can you access data bases, save programs to tape, or use non-Commodore devices? What you need are peripherals. But which peripherals? What do they do? How do you hook them up, and how do you use them once they're connected? Commodore Peripherals: A User's Guide answers those questions. It's the first comprehensive guide to the myriad of Commodore peripherals available for the VIC and 64. From Datassettes to modems and interfaces, it clearly explains each device and tells you what it can do. 
The peripherals documented in this book include: 
• 1541 disk drive 
• VIC-1525 graphic printer 
• VIC Super Expander 
• CP/M for the Commodore 64 
• Model 1600 VICMODEM 
• 1530 Datassette 
• And others, from memory expanders to printer Iplotters. 

This book covers the advantages, principles, and details of the disk systems for the Commodore 64. It sets out the ordinary actions of LOAD and SAVE, machine code loading and saving, and the special commands that are peculiar to disk systems. The actions of filing are explained in detail, since filing on disk is such an important feature of business and other database applications, and available disk utilities are reviewed.

The advent of inexpensive, reliable disk drives for home use represents a revolution in what can be achieved with a microcomputer. Any computer, no matter how large or small, comes into its own only when it is able to access data far more quickly than can be achieved with the trusty but tortoise-like cassette drive. Without fast mass storage, substantial programs become tiresome burdens which can take up to 15 minutes to load. The handling of data becomes a nightmare, with its constant necessity to rewind or change tapes and the wait while data is slowly added to memory. In short, the best computer is only as good as the means it uses to store data. The disk drive is far from a luxury, it is an essential component of an effective microcomputer system. Nowhere is this more true than in relation to the Commodore 64. The success of the 64 as far more than a games machine or a computing toy is based to a large extent on Commodore's ability to produce a disk drive which works to the highest standards and yet is within the price range of anyone who takes their computing at all seriously. But simply to buy a disk drive is not the solution to the problem of enlarging the scope of the 64. Like any disk drive, the 1541 has its own way of working, and its own habits which are neglected at its owner's peril. Poorly thought out working methods with a disk often mean that much of its potential can remain unrealised. Carelessness, or lack of understanding, can mean that valuable data or programs are irretrievably lost. And yet, for all that, the 1541 is a well designed piece of equipment, full of features that many disk drive owners can only dream about. This book is an attempt on our part to share some of the many discoveries that we have made about the 1541 disk drive, the enjoyment that comes with using it and the power that is released when it is used well. 

By public request the author has compiled this maintenance guide. This guide contains the following excerpts from the "1541 Single Drive Floppy Disk Maintenance Manual":
 •Calibration (including head alignment) 
•Troubleshooting Part I (for the novice) 
•Schematics and Parts Layout (reference data for those with experience)

This book is intended to help you make more effective use of your Commodore disk drive. Although the examples and program listings are designed for use on a Commodore 64 or VIC-20 with a 1541 disk drive, many will work without modification on other Commodore computers and disk drives. This book expands and clarifies the documentation provided by Commodore Business Machines, Inc. Some of the information covered in the 1541 User's Manual is also presented here. However, the majority of information presented in this book is original and is the result of intensive research and testing by the author.

This manual is intended to supplement the documentation provided in the 1541 User's Manual. Although this manual is primarily designed to meet the needs of the intermediate to advanced programmer, it will also be of interest to the novice Commodore user who wants to know more about how his 1541 disk drive works. This manual is not intended to replace the documentation provided by Commodore Business Machines, Inc. and the reader is assumed to be relatively familiar with the contents of the 1541 User's Manual. For the sake of continuity and clarity, some of the information covered in the 1541 User's Manual is also presented here. However, the majority of the information presented in this manual is original and is the result of intensive dis-assembly and annotation of the 1541's DOS by the authors. Some information is based on articles and notes published in a variety of publications as well as discussions with other knowledgeable disk experts. This manual was not prepared with the assistance of Commodore Business Machines, Inc. Although we cannot guarantee the accuracy of all the information presented in this manual, the material has been thoroughly researched and tested.

There were several reasons for writing Inside Commodore DOS:
1. To correct errors and omissions in the 1541 User's Manual.
2. To help you make more effective use of your disk drive.
3. To provide complete information on diskette formatting.
4. To provide complete information on the storage of files.
5. To allow you to read and write data in non-standard ways.
6. To help you make a backup copy of your "protected" diskettes.
7. To help you recover damaged diskettes.
8. To help you understand the operation of your disk drive.
