* '''Board: Prototype with Gate Array Simulator'''([[CPC Prototypes|more picturs]])
* The Gate Array Simulator board (mounted on top of the mainboard, and almost having the same size as the mainboard) contains four 8K EPROMs, and a Gate Array prototype made of several logic chips. In later versions these evolved into a single 28pin 32K ROM chip, and the usual 40pin Gate Array chip.
