[GreenKeys] Model 15 troubleshooting

[John Nagle]

    The machine is now typing.  I've typed the alphabet, numbers,
and all the special symbols without error.  Thanks, everyone.

    Error rate is around 1-2%, just typing manually in loopback.
So some minor adjustments are still needed.  And there's a oil
leak near the left end of the main shaft. But the basic machine is
now working.  The little stuff I can deal with.
