Congratulations on purchasing one of the most advance copiers for the Commodore 128 computer and 1571 disk drive. Many month of research have gone into developing this copier. Before we start, | must say a few words about copying software. This software has been designed strictly to allow the user to make legal archival backups. When copies are made and distributed illegally, the software industries losses money. If this happens, software authors may be turned away from developing software.

CMD gateWay 128 Addendum

CMD gateWay 64 Addendum

It is important to understand that the gateWay is more than a replacement deskTop - the gateWay represents a whole new philosophy for working with GEOS.  From the creation of a new boot disk, to disk drivers and thegateWay itself, a new level of sophistication is brought to GEOS.

CMD gateWay v2.5 Addendum

Introducing geoCanvas, the alternative paint program for use with GEOS 64 v2.0 and GEOS 128 v2.0.  geoCanvas provides GEOS users with many features previously unavailable in a drawing program, and we hope that, you will find them exciting and useful.  In addition, the ScrapCan utility supplied with this program also provides a long-needed function - the ability copy and paste large scraps with color.

CMD Perfect Print LQ Enhanced Addendum

Until now, there has been one large drawback to the GEOS system - the printout.  After carefully creating a stunningly attractive document in geoPaint, geoWrite or geoPublish, the inferior quality of the printout caused WYSIWYG to become WYSWMYG (What You See Will Make You Gasp!).  There were really only two alternatives.  Either put up with the poor results, or turn to other, more complex programs which offered better print results without GEOS.

Perfect Print was designed to solve this problem. This package consists of the GEOS LQ Print System for geoWrite and a collection of powerful HQ interpolation printer drivers for the other applications. The Print System expands geoWrite (the most used application in GEOS) to new printout dimensions.  Documents created with geoWrite can be printed out in the highest possible quality allowed by your printer.  Printouts of 240 x 216 dpi(dots per inch) on 9 pin printers and 360 x 360 dpi on 24 pin printers are attainable.  Special fonts are included which support the high resolution ofthe printer and make high quality printouts possible. While the end result does not quite reach laser printer quality, it can certainly be compared.

This is a summary of the utilities with descriptions for the software that came on the 1993 version of CMD Utilities.  

This package includes a number of new and improved utility programs for use with CMD hardware and other Commodore-compatible peripherals.  We feel certain that you'll find many of the programs useful in the daily use of your system.

WELCOME TO COCO 2!

CoCo2 is a tool for developing video games for the VIC-20. Think of it as a sort of SEUCK for the VIC. Why is this program called COCO 2? Because there is a COCO. The first COCO teaches computer techniques, computer programming, a basic language and problem solving. COCO 2 allows you to create your own computer games. But COCO 2 really does much more.

By the time you have played and programmed with COCO 2 you will have learned:

• Computer Graphics
• Computer Animation
• Real-Time Programming
• Computer-Human Interaction
• Logic

And you thought you were just having fun!

This manual was written to be unique and useful as the CODEWRITER SYSTEM itself.  This Is a tall order. Please believe us when we say that everyone at Dynateoh Microsoftware worldwide has worked to make CODEWRITER among the most valuable programs you can own.

This BBS program is written mostly in BASIC with just enough machine code to allow a 300/1200/2400 baud modem to transmit and receive at full speed. The main purpose for writing a BBS in BASIC is for ease of modification by the you the SYSOP. If you can do a little BASIC programming, then you should be able to make almost any changes to the BBS you may want. But if you ever do need or want any help in a making a modification, feel free to ask me about it.

Michael “Nuke” Newkirk reached out to me this week to let me know he has something special to share with all you Color 64 sysops out there - a revised and reformatted manual for the Color 64 v8.0 BBS!  I'm sure you'll appreciate the time and effort that went into this project, thanks Mike for keeping the Commodore 64 BBS dream alive. 

Here is an excerpt from the foreword of this revised manual.  I highly encourage taking a few minutes to read it, because if you were ever a sysop, you will completely relate:

"This document is a capture of the last Color 64 v8.0 txt that is widely available on the internet. I wanted to reformat it and make it an easier table-driven reference as much as possible for my own personal use, and the idea grew to make this something more with distribution to the interested communities in mind. I tried to keep to the author’s original personality and content, but invoked many grammatic changes and some technical that I felt would better serve the new generation of SYSOPs coming in."

Thanks Mike (Nuke)!

Manual updated 4/8/2024 - Some minor tweaks and corrections - See page 160 for editor's notes on CMD HD usage.

The C O L O R 80 program turns on the hires bit map mode described in the Programmer's Reference Manual (start page 122).  The screen starts at $E000 (57344 decimal) and the color starts at $D800 (55296 decimal). To poke into color memory, first switch out I/O.

Mastercode is a substantial and complex program, providing a host of features of use to anyone interested in machine code programming on the Commodore 64, Despite its complexity Mastercode is designed with the user in mind and is far easier to use than many inferior assembler/disassemblers. All of Mastercode's many facilities are called up by means of clear menus and prompts which appear as the program runs. There are no obscure commands to enter to make full use of Mastercode and with an hour or so's practice you will be making the most of its power.

Our friend Tomse over at retro-commodore.eu was kind enough to reach out and share this Commodore 64 treasure with us.  Not only do we have the beautiful scan to share, he also made images of the two original disks that come with the package.  These are pretty rare as only a cracked version with some missing files has been spotted over at csdb.dk.  The two .d64 disk images are imbedded in the PDF file, but I'll also post them as a seperate download. 

Thanks Tomse!

Welcome to this revised expanded manual for the excellent music tracker SID-Wizard2 for Commodore 64. I will try to go into detail of most aspects of the tracker and I will also try to explain the functions of the wonderful SID chip as we go along. The reason why I expanded the work of Mihaly's manual is that there is some stuff left out that SID gurus know but beginners don't.

This guide covers SID Wizard versions up to 1.6 and is still helpful with 1.7 & 1.8, but version 1.8 has many changes compared to 1.6.
