I am not a Luddite, but I know that it's possible to embed the equivalent of
"bad guy magic" in electronic systems. Please show me how you would tell the
difference between a real Z80 CPU and one that's labelled the same but that
contains an ASIC that emulates a Z80 -- and that adds a few "extra" features
that are activated by, for example, keying the phrase "Open Sesame" in
MSB-first ASCII into the A0 line using 12V 2-nsec pulses with 10-nsec gaps?

Please be specific about the time, people, and other resources you would need
to discover this newt's-eye's-worth of "bad guy magic."
