* '''CPC 664 Keyboard Circuit'''
* Mitsumi KPR Type Keyboard similar to the [https://deskthority.net/wiki/Commodore_Amiga_500#Mitsumi_KPR_Type Amiga 500]
* Single foil (with 19pin connector).
* Connections are closed when the key touches the contacts on the foil.* Amiga 500 Plungers work, but the central hole is a little bigger, a little adhesive putty allows the smaller prong on the keycaps to fit.* Not actually a membrane keyboard (since the foil doesn't move), seems to work more like the old PCB keyboard.
