Work has begun on the non destructive VIC-20 Raspberry Pi conversion kit. Similar to the C64 breadbin, this it comes with a complete framework that connects to the original board mounting locations in the VIC-20. You may choose to use the icomp Keyrah v2 to adapt the keyboard of the VIC-20 to the Raspberry Pi, or you may choose some other option. Two different port access plates are supplied in the kit. One with the factory openings, and the other specifically designed for the Keyrah v2.
Here are some initial photos of the actual printed kit, test fit in a Commodore VIC-20 computer housing.
