[Elecraft] Very dumb mistake

Senility. I was trying to repair my KRC2, which had a damaged voltage 
regulator and one of the driver chips. I put the new regulator in 
backwards (yes, I did this) and as a result applied about 10v to the 5v 
microprocessor.

Now the voltage readings at the processor pins are very different from 
that specified in the manual.

1. Did I destroy the processor?
2. Is there a simple way to tell?

This is depressing, because it took about a month for the replacement 
driver chip to get here.
