* Project Number 19 - Amstrad Expansion System Part 2: describes the 6 x 8-bit parallel I/O Port and PSU Card(see [[Maplin ROM Box]], too.)* Project Number 20 - [[Maplins 8bit Input Port|Amstrad 8 Bit Input Port]]

Additionally, some "general purpose" projects can be customized for use with the CPC (and do include info on how to do that) (for example, the [[Maplins Weather Satellite Receiver project ]] includes CPC source code). The projects have been offered optionally as plain paper (schematic & instructions), in kit form (components and PCB), and as fully assembled circuit.
