At the risk of sounding fundamentally stupid,
what's a tempest machine?
At the risk of duplication I will relate the story as I heard it years ago.
Some "ham" type guy basically tells a military type guy, "Your security
stuff is doo doo, let me show you something." Then he takes the guy in his
van and parks across the street from some defense plant, fiddles with ham
stuff and a directional antenna, and duplicates on a crt in the van the
images from the crt on several different systems in the defense plant. The
military guy naturally goes ape sh, er gets excited, and the result is
tempest, or PC in foil, aka no rf leaves the plant.
