Following is the keyboard wiring to connect to the 22-pin internal
connector in the 400. I have a picture which I will be happy to send
USPS on request.

I made a photo-copy of the keyboard from the back of one of the
manuals and glued it to the keytops where an Atari-specific change was
requied. The paper does eventually wear off; putting clear tape or
clear plastic spray on top helps. I also tried painting on the keys,
but tt was less satisfactory.
