Well, I once ripped the metal lids off a few ceramic DRAMs to use them as
optical image sensors (ISTR an article in BYTE, I think it was, years ago
about that), and there's a story about how Ferranti designers determined
that a particular ULA design worked perfectly if only you could get at the
gates with a microprobe to add a pullup in a certain place, but these SRAMs
are plastic and I've run out of fuming nitric acid :-(
