System Specification for C65
March 1, 1991
This specification describes the requirements for a low-cost 8-bit microcomputer system with excellent graphic capabilities.
1.1 System Concept
The C65 microcomputer is a low-cost, versatile, competitive product designed for the international home computer and game market.
The C65 is well suited for first time computer buyers, and provides an excellent upgrade path for owners of the commercially successful C64. The C65 is composed of concepts inherent in the C64 and C128.
The purpose of the C65 is to modernize and revitalize the 10 year old C64 market while still taking advantage of the developed base of C64 software. To accomplish this, the C65 will provide a C64 mode of operation, offering a reasonable degree of C64 software compatibility and a moderate degree of add-on hardware and peripheral compatibility. Compatibility can be sacrificed when it impedes enhanced functionality and expandability, much as the C64 sacrificed VIC-20 compatibility.
It is anticipated that the many features and capabilities of the new c65 mode will quickly attract the attention of developers and consumers alike, thereby revitalizing the low-end home computer market. The C65 incorporates freatures that are normally found on today's more expensive machines, continuing the Commodore tradition of maximizing performance for the price. The C65 will provide many new opportunities for third party software and hardware developers, including telecommunications, video, instrument control (including MIDI), and productivity as well as entertainment software.
