OK, so you made me try it ;) and I got an interesting result

"just to see" I thought I would use it to read a 16f88 I had on a board
with the appropriate PICkit header.  Took a couple of minutes to figure
out the switches, but once I did it seemed to work just fine.

But then I got curious.  I was powering the board from the programmer,
and wondered if I could put a decimal voltage on the command line, like
say, 4.5.  Well all looked good until I diffed the 5 volt and 4.5 volt
hex files.  They were different!

So, I did both again, and the two 5 volt files were the same and the 4.5
volt files matched, but the two voltages had different hex files.

Looking closer, it wasn't that the content was actually different, but
there was one line, which appears to be the configuration fuses, in a
different place in the file depending on the voltage!

The mysteries of Chandler, I guess.
