RE: HP 71B broken
With the 71 open, measure the continuity in each trace of the flex cable. If there are any open traces then you can solder a small wire (30 AWG) in parallel with the open trace. Consider replacing the cable with discrete wires, which was HP's solution. I also have a metal-backed 71 with a cable replacement. I can post a pic later.
