[1] One classic is that a device has to be immune from

be used only by the constructor (who possibly doesn't care if he has to
reset it after a zap) at a static-safe bench (so the possibility of a zap
is minimal anyway). But if I build something that doesn't comply with
that regulation, as I understand it, I am breaking the law.
On an unrelated vien, I've often thought about tracking down an old
tempest PC case, removing the guts and installing something smaller but
more modern -- FDDI, 100Base-FX or 1GigE over Fiber -- and putting a big
RAID array in it (big -- three 120GB IDE drives[0]) and using it for EMP
resistant storage. Lightning is EMP, after all. :-)
[0]: No comments from the peanut gallery. I already know about IDE's
reliabily and potential problems first-hand.
