One of my favorite stories (I've got a million of 'em) from the olden days
was when I was sitting at the good ol' Intel development system, programming
a 2708 with the latest and greatest.  An assembler happened to be standing
there, and said "Wow!  Those things get real hot when they're programmed,
don't they?"  I looked up, and sure enough, the EPROM was red-hot and
backwards.  Pulled it, and programmed another, but later, out of curiosity,
tried the "red-hot" one again.  Programmed perfectly, and worked just fine
from that point on.  I was impressed (but not enough to use it in a 
production unit!)
