Very helpful!  It looks like the pins are wrapped around to touch traces on 
both sides of the ceramic - is that correct?

Assuming that the later (discrete SRAM) Zips had a similar internal 
arrangement, this doesn't look too bad.  If I go in with a Dremel bit just 
inward of the plastic housing, I should be able to open things enough to spot 
the edge of the circuit board before putting the bit through a trace (my 
primary fear).

I'm still going to try for an X-Ray image of mine, but this gives me a bit 
more confidence.
