This project has become such a major part of the site I've added a section of its own to keep everything together. This page has links to files and documents that sum up the project. This is a great place to start, other articles can be found in the Z80 Project tab below this entry.
All the latest source and schematics is going to be kept in the GIT repository, check it out new versions of the code and documentation are all available there.
