We also ran into a VT52 (I think, although possibly it was a VT100) which
apparently had been TEMPEST secured; the inside of the casing had been
coated with a metallic film. (Or perhaps it was built to operate in
an environment with a high E-M radiation level, and kept stuff out, not
in.) I don't recall anything else about it now, alas - it's been almost
40 years!
