The Cody Computer is an 8-bit home computer intended to be built as a DIY project. Inspired by (but not compatible with) the Commodore home computers of the 1980s, it's built around the Western Design Center's 65C02 and 65C22 and the Parallax Propeller microcontroller. It doesn't compete with your modern computer or even the new incarnations of old computers. Named in honor of a good little boy who preferred museums, rockets, and computer chips to chew-sticks and squeak-toys, it's just supposed to be simple, silly, fun, and perhaps a little bit educational.
The electronics were designed using KiCad and the mechanical components developed using OpenSCAD and Inkscape. The assembly-language software was written using the 64tass assembler, while BASIC programs were written using the bespoke Cody BASIC interpreter. All design files and software are released under the GPLv3 license. If you don't build one yourself, perhaps it'll give you ideas for a work of your own.
Detailed project information is available in The Cody Computer Book, a freely downloadable PDF currently available to review as a draft copy. Additional content covering Cody BASIC programming, assembly-language programming, and electronics projects for the Cody Computer will (hopefully) be available in the future. Any future content will also be available online and without charge.
