It incorporates an amazing variety of features, at a price of less than $300. Some of these features represent firsts in the computer industry. The Commodore 128 is, of course, the first upgrade of the ubiquitous Commodore 64 computer, of which over three million have been sold to date. The Commodore 128 is the first low-cost personal computer to offer a full one-eighth megabyte (128K) of memory. It is also the first computer to combine the high reso­ lution color graphics of the Commodore 64 with a serious business oper­ ating system (CP/M). The Commodore 128 is the first computer to offer two entirely separate microprocessor brains and video graphic chips, giving it essentially two different personalities: home computer and small business computer. It is also the first low-cost personal computer to offer an intelligent disk drive capable of reading dozens of storage formats. Finally, and most importantly, it is the first computer to combine, in one case, what amounts to three separate computers: the C64 mode, the C128 mode, and CP/M mode.

The module information in this data pack is organized into the following sections: • Module Overview • Applications • Installation • Cabling • Module Configuration and Control ° Front Panel Controls and Indicators ° Avenue PC Remote Control ° Avenue Touch Screen Remote Control • Troubleshooting • Software Updating • Warranty and Factory Service • Specifications 5280-1 Model 5280 Video DAC MODULE OVERVIEW The 5280 module converts serial digital component video into composite analog video. Six separate composite or two Y/C (S-video) analog video outputs are available. The following analog formats are supported: • NTSC Composite with or without setup • PAL Composite A serial output BNC is provided for applications requiring the serial digital input signal to loop-through to another device. Output timing can be adjusted relative to a reference input signal by installing the 5210 Genlock Option, a submodule that plugs onto the 5280 circuit board. Incorporating a full- frame synchronizer, the 5210 also allows the 5280 to accept serial inputs that are asyn- chronous to the reference. As shown in the block diagram on the following page, the serial digital input signal first passes through serial receiver circuitry then on to EDH processing and deserializing. The serial output signal goes to a cable driver and is then AC coupled to a loop-through output BNC on the backplane.

  • Commodore 64 Users Guide
    INTRODUCTION Now that you've become more intimately involved with your Commo- dore 64, we want you to know that our customer support does not stop here. You may not know it, but Commodore has been in business for over 23 years. In the 1970's we introduced the first self-contained per- sonal computer (the PET). We have since become the leading computer company in many countries of the world. Our ability to design and manufacture our own computer chips allows us to bring you new and better personal computers at prices way below what you'd expect for this level of technical excellence. Commodore is committed to supporting not only you, the end user, but also the dealer you bought your computer from, magazines which publish how-to articles showing you new applications or techniques, and . importantly . software developers who produce programs on cartridge, disk and tape for use with your computer. We encourage you to establish or join a Commodore "user club" where you can learn new techniques, exchange ideas and share discoveries. We publish two separate magazines which contain programming tips, information on new products and ideas for computer applications. (See Appendix N). In North America, Commodore provides a "Commodore Information Network" on the CompuServe Information Service . to access this network, all you need is your Commodore 64 computer and our low cost VICMODEMtelephone interface cartridge (or other compatible modem). The following APPENDICEScontain charts, tables, and other informa- tion which help you program your Commodore 64 faster and more efficiently. They also include important information on the wide variety of Commodore products you may be interested in, and a bibliography listing of over 20 books and magazines which can help you develop your programming skills and keep you current on the latest information con- cerning your computer and peripherals.

Introduction Commodore BASIC 4.0 is the most sophisticated software developed for the CBM com- puter line to date. Programs are of course upward compatible from previous Commodore BASIC releases but both the user and the programmer can enjoy new features of 4.0 The first Commodore BASIC, version 2.0, was released in August 1977 for the PET 2001-8 computer. Version 3.0 in July 1978 added a machine language monitor and corrected known bugs of version 2.0. Version 3.0 is standard in all 2001 series since July 1978. Version 4.0, completed in October 1979 included all the improvements of previous releases, enhanced the speed of string processing, and integrated disk commands into the BASIC language. BASIC 4.0 is standard in the CBM 4000 series and the CBM 8000 series. It is also available as an upgrade for CBM 2001 and 3000 series.
