If I know for sure that these are the processors that need that block of
code, your suggestion makes perfect sense.  Unfortunately, I don't know.
My primary goals are

1.  Put a stop to this thread (so far I have failed miserably)
2.  Document that block of code.
3.  If it makes someone's life easier.. it would be a bonus.
