Hello,

Just a quick query.  Before the 16c84 was superseded by the 'f84 I had
bought quite a few �84's.  These have found there way into a number of
projects.  I still have a few left.  I was programming one this morning.
Admittedly it has seen a lot of write cycles, but nowhere near the quoted
minimum.  I can read the program memory, but it won't allow a write of the
program memory.  The data eeprom and config fuses can be read and written.
Has anyone else experienced early demise of these parts?  Admittedly they
are superseded, but just out of interest.

Cheers
JD
