The first case is flat out impossible to protect against. Any debugger
that can single step will be able to read the EPROMS, and worst case,
a modicum of extra hardware could easily snoop out the contents of the
EPROMS (they have to be read during instruction/data fetches anyway, and
you can just monitor the address and data lines).
In addition, it's foolish. If it's possible to write a program that
trashes the EPROMS, what happens if, just by accident, System 7.0 just
happens to do this? Ooops.
Bottom line; assuming they have a real product, they will lose more sales
because of pissed off customers trashing their EPROMS (plus god knows how
much $ spent in support) than they will from pirates stealing the EPROMS.
