No joke.
This would have to be a ceramic type DRAM chip to be
decapped by an
individual (easily).
Yes.
Does anyone know what I'm talking about or have
the document? I thought it
sounded fun. : )
I do not know the document, but I did run across it (or one like it)
and did decap a ceramic 4116 sometime in the mid-1980s (it had to be
1984 or after because I mounted the DRAM in an Apple II, and I didn't
have one on-hand until 1984-1985).
I never stuck a lens in front of it, but I did play with the
light-sensitivity of the chip.
