I've added two images of the Zip Chip II - 4Mhz that I had the bottom peeled off of it, to the gallery at http://16sector.com
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.
