Some years ago I thought to design a personal computer which had a few
unused bits in some of its I/O latches for hackers to discover. When
they set one of these, it would set off a smoke bomb disguised as a
capacitator on the mother board.....

Then there was the video board I bought from Fry's which did actually
emit smoke when I powered up my PC. But that's another story....
