Is this check for signedness a hardware thing or a software thing? Could an
approach like the HW2Patch for the TI-89 be used to override any check for
a signed application?  If it is software, I don't see how a new OS could be
prevented from being put on the calc if you used a custom link program and
did a total wipe of the flash chip ahead of time (hold a hot line to the
pin on the chip, if necessary)
