C-One

The C-One is a single-board computer created in 2002 as an enhanced version of the Commodore 64, the home computer popular in the 1980s. It was designed by Jeri Ellsworth and Jens Schönfeld and built by the German company Individual Computers. Instead of fixing one hardware design, it uses configurable Altera field-programmable gate array chips together with modular processor cards, so that a core file loaded from a card rebuilds the logic of an older machine in hardware. This makes it a hardware recreation rather than a software emulator. Its default processor is the W65C816S from Western Design Center. Cores followed for the Amstrad CPC in 2004, an improved Commodore 64 core in 2006, the Amiga 500 through the Minimig design in 2008, and the Chameleon 64 preview in 2009. The same programmable logic can also host entirely new computer designs.
