    Steve: This is a good idea of placing a global copy-protect disable in
    the software; much easier than changing the silicon.

    However, I should point out that CUSTOMERs are often the people that
    you want to protect the device from. Ie, you are a small developer
    working for Honcho Technology and send hem your working prototype.
    They read out your code and sever the contract. It could happen.

    In this case, it is usually better to include the price of a couple
    OTPs in the contract...

    two cents.  The cheapest thing to change is software.  I would
    interested
    in a programming suite of tools geared specifically at the development
    environment.  I would like programming software that does not allow
    the
    protection bits to be set ever.  This development software would never
    code protect a part.  During development we could use this safe
    version,
    for customer prototypes and production we could use full featured
    programming software.

    Here is an opportunity for all the folks writing programmer software.
     Make us a version that will never intentionally set the code protect
    bits.  I would gladly pay the cost of a few JW packages just to be
    sure
    that I did not choose the wrong option.  I know that programming
    errors
    can occasionally inadvertantly code protect a part.  However,  if we
    can
    eliminate operator error, I think we can save quite a lot of chips!

Only problem is, Honcho Technology probably resides in someones garage
and,
after paying the usual extravagant lawyer's fees, cannot afford the
'blow-and-go' sessions. (especially on the JW part)
