Many thanks for the suggestions.  I've got a lot of evenings to pass
sorting the box.  I'll let you all know how things go.
Back in the day, I once tested a 2732 as Chuck suggests and got an Intel
symbol tattoo on the end of my right index finger for it.  It was
readable for quite a time before my fingerprint came back.  If I were of
the bad guy persuasion, it would have been interesting to see the
fingerprint card.  Maybe burn in a Signetics symbol on another finger,
and AMD and Harris on the rest.  Not recommended.

 I've seen them survive that (though I
don't recommend doing it on purpose).
  But as I said, UVEPROMs are pretty rugged things.
 Indeed.
