+Also, if you are using a real keyboard foil then you need the connectors, the actual connectors you need are Molex parts 22-02-3053 and 22-02-3083.
+Note when soldering that you solder them in with the correct orientation, as the two foil ends are metalized on diferent sides, and so the 5-pin 22-02-3053 should be mounted 180 degrees rotated compared to the orientation of the 8-pins 22-02-3083. If the orientation is wrong the connectors will not make contact with the metalized side of the foil. You can fi9nd these connectors from different distributors, or from https://www.sellmyretro.com/offer/details/set-of-molex-keyboard-membrane-connectors-for-sinclair-zx81-10859
