Most of the keyboards that I have access to are
much older, many of then from Apple. There is
only one PC USB gaming keyboard and mouse, not
that they were ever used for such. There is
just the one RPi keyboard and mouse.

I used the more modern, fairly common keyboard
because trying to figure out if old equipment
related failures are actually the same type of
failure did not seem reasonable. Trying to
match old equipment for comparison/contrast
activities did not seem reasonable either.

That the modern keyboard happens to be an RPi
one is an accident.
