"The more interesting debate was in Circuit Cellar, about microcode
safety.
A really good read.
Is it really possible to crack the PIC (16C84) so easily? Scary."

The above was posted in another thread, would somebody be kind enough
to let me know the jist of the article please. Is Circuit Cellar an
american magazine?

Discontinued. The 16F84 is also a poor choice, because more recent
parts are both cheaper and better. Yet so many hobby projects were
written using the older parts it continues to be mentioned.

It's a magazine (a spinoff, a long time ago, from Byte Magazine), but
that sounds like something on one of their web site's discussion forums.

As I remember the same sort of stuff here on the newsgroups, there was a
overvoltage pulse sequence that could reset or burn out the protection
fuse so that the contents could be read out. Not a 100 percent thing,
but it worked frequently enough to be useful.

A lot of that stuff came from the people cracking the Satellite TV
subscription cards in the UK and Western Europe. Or the people
cracking the cracks.
