Quick update and proviso:  A low-profile socket isn't going to work with a 
ZipChip!  The package extends too far on the ends and will interfere with the 
actuating lever :-(.  I'm going to have to go for the conventional ZIF socket 
with side-mounted lever.  That's going to neatly prevent anything from sitting 
in slot 3 and perhaps slot 2 as well.
