Apple Newton Keyboard Fixed

I love a happy ending. I now have a working keyboard. Ages ago I bought some electric paint, and it worked a treat. I just had to scrape off an insulating layer and then spread the paint all over the track to restore the connection and make a fix.

A smoking gun if ever I saw one. You can see the gap in the top track of the membrane at the bottom of the picture. I thought the green covering the ribbon cable was another layer of tape stuck onto the back of the keyboard membrane, but actually it is a layer of paint. So I scraped it off around the break and then clarted the whole thing in conductive paint. And it fixed the problem. The hardest part was getting the keyboard mechanism back in the case. That took two goes.

Many thanks to the folks behind this site, which told me how to take the keyboard to bits.
