So the objective here was to take a C64 breadbin case and keyboard and put a Raspberry Pi 3 into it; keeping the keyboard and joystick ports working, but also giving me HDMI, USB controller support, and modem emulation. While I still have 2 real Commodore 64s (and an Ultimate64 on the way!), I like using the RPi and Vice to play 64 games.
These mounts do not require you to drill or cut your C64 case! The 3D files are provisioned under the creative commons license so they are FREE to use, distribute, modify, or even sell.
Just a fun project.
