The fancy chip inserter slipped , and I had to make
a grab for the PIC. Then I inserted the PIC onto the
breadboard and powerup.

Tum te tum. 20 sec+

Nothing. Poweroff. Have a quick look. Pic has been
inserted the other way around. Smack forehead and turn
it right way round. Program runs.

I tried reprogramming it with another program. That works
okay. Goody.

How do I know if there was no internal damage ? The device
is a 16F84-4. Anyone got code and hookup that will ascertain
that all is well? Every port and timer ? Every programming
location and ram and other oscillator setup? You know , put
it through the paces . Anyone did something like this ? And
for testing other devices ?

Probably I will retire it to some circuit that will not require
anything in reliablity and get a 16F628 . Hey maybe even a HVP/LVP
programmer for a 16F628. Quite trivial.
