Flea Market Finds #6

Yesterday I picked up an external ZX Spectrum keyboard and two Game & Watch games (Mario Bros, Donkey Kong II - boxed). It would seem I should have picked up the Spectrum as well because I'm missing two flat cables that go from the edge connector to the mainboard keyboard connectors. It's pointless thinking about it now because the Speccy was sold less than an hour after I bought the keyboard. I will obviously have to produce the cables myself although I have no idea how I'm going to connect them to the mainboard. Soldering the cables directly to the motherboard is out of the question. Tried googling for more info on the keyboard with no success.
