Harlequin Schematics
Please credit the original author, Chris Smith, and provide links to this Blog in any works or projects that derive from the contents of this Blog. This not only ensures that your readers have access to the full development history of a project, but also politely attributes credit where due.
The schematics for this project will evolve over time, as will this blog. It will be important to make available all versions of the schematics as they represent points in time and key phases of the Harlequin design.
Schematics and versions are listed and downloadable below. The schematics with the same version numbers are at the same stage of development, and should be viewed together. For a complete set, view the highest version numbers of each file.
