Pimmodore-64 is a Keymmodore-64 spin-off. This project is completed. Unfortunately, the kind of USB cables in the pictures are not available any more so I’ve done a new version with other cables.  Will be published soon.

Anyway, you need to read about Keymmodore-64 first in case you haven’t. Also if you can’t wait, here you have the Bill of Materials and the Sketchup files for 3D Printing.
