This is a faceplate for the ZX Cartridge 2.021, a cartridge designed to be used with the ZX Interface 2.021 - a new cartridge interface for the ZX Spectrum 16k/48k machines. Using a cartridge faceplate means that the cartridge sits correctly in the interface, ensuring that wear and tear on the connectors is kept at a minimum. Well, mostly it just ensures that it looks pretty while the cartridge allows you to load cartridge programs on your ZX Spectrum.

I'll be creating a whole selection of cartridges for the interface, have a look at my PCBWay Shared Project for a filtered list of all shared projects that's related to this interface. For documentation, including the BOM, build instructions as well as everything else that you'd need - check out the github-repository.
