Unless of-course my chip has a PROM with the desired o/p, senses the
(key,input) pair, and spits out the desired o/p. This is fairly
easy to do. THe easier thing to do would probably have a 'test my phone'
800 number that you can call, which has a trusted CLIPPER chip, and which
will verify that your chip is a real CLIPPER.
