C-One

The C-One is a replica of the 8- bit home computer C64 Commodore from the 1980s. The American Jeri Ellsworth began in 2000 to a complete re - design of the C64, which resulted in co-operation with individual computers in 2003 in the delivery of the first C-One board in ATX format. Meanwhile, Jeri Ellsworth is no longer involved in the development.

For the design are standard components use. The processor is an 65C816 compatible with the MOS 6502 CPU comes with a clock frequency of about 20 MHz, 24- bit address space and an expanded instruction set for accessing memory above 64K used. For real time run old C64 software programmed brake provides. The C-One also has a processor slot, through the means of an adapter board almost any arbitrary 8- bit processor can be upgraded, such as a real MOS 6502 or Zilog Z80.

The C-One is considered the first reconfigurable computer: The functions of the custom chips of the C64 are in the C -One hard-wired ( hardwired ), but can be reprogrammed ( reconfigured ) are. Used for the C-one two field programmable gate arrays (FPGA). Thus, the C-One can also have other 8 -bit computers such as the Schneider / Amstrad CPC hardware technology to imitate. Meanwhile, there is also the project NatAmi, is used in the first prototype of a C-One to emulate an Amiga with 32- bit CPU 68060. In this project, but the development of their own hardware is planned for later.
