* '''CPC 664 Keyboard MembraneCircuit'''* Single "membrane" foil (with 19pin connector) (Seems to work more like the old PCB keyboard).
* Connections are closed when the key touches the contacts on the foil.
* Not actually a membrane keyboard (since the foil doesn't move), seems to work more like the old PCB keyboard.

* '''CPC 6128 Keyboard MembraneCircuit'''
* Two membrane foils (with 2x10pin connector)
* Connections are closed when the key presses the two foils against each other.

* '''CPC Plus Keyboard MembraneCircuit'''
* Two membrane foils (with 2x10pin connector)
* Same as in CPC 6128, but with connection cable at rear side.
* '''KC Compact Keyboard Circuit'''
* PCB with real mechanic switches, possibly the most robust CPC keyboard, even more robust than the early 464 PCB keyboards. Only downside is that it lacks the F5..F9 keys.
