I figured I was not the first with the idea.  Truly, though, I had not 
seen it in his store.  Guess I'll have to see what all is there, so as 
to not reinvent the wheel all the time.

I thought about that, but I don't have a PET set up here, and was 
worried that the height of the IEEE connector was more than the distance 
from the edge connector on the PET to the table surface.  If someone has 
one set up and can measure it, I'd appreciate it.

I actually have it already, but I redid it for the reason listed above.  
But, if it's known the connector height is OK, I agree, the upside down 
footprint is better.
