AVR-Chat

Thanks for the suggestions about the atmega8515 - unfortunately it has to be a straight 
plug-in replacement. I am not allowed to touch the code (even assuming the correct 
source version could be located...).
As an aside, there are actually two completely different pieces of hardware, in two 
different companies both using this chip. The first has not reported any failures - but I it 
would not hurt to have a couple of spares available. I have a unit on the bench from the 
second site, where the program has been corrupted, and even re-programming and 
verifying, it does not work in the pcb. I suspect it might have been damaged by static - 
there is a smartcard socket on the pcb so there is a possibility that this is an entry point 
for static charge.
