This is the PCB to build a set of loopback connectors to use the VIC 20 Diagnostics cartridge (not included).

The PCB is supplied all in one piece, and needs to be broken apart to make the separate sections for the keyboard, userport, datasette and joystick loopbacks. Instructions and parts list are provided - see link below.

More information on my blog:

This auction is for a PCB only. No connectors or other parts are included, nor is any form of cartridge, which will be required to run the diagnostics - see this article for a few options.
