We had a network of serial lines extending for several km over a few
suburbs; after every lightning strike I would get to replace the 1488/1489
chips which were *soldered* in.
Eventually I just bought a set of high-quality sockets, and merely swapped
the chips as each terminal came in after being zapped by Thor.
As an aside, not only did I chuck out the bad chips but I took care
to bend their pins over backwards, in case some idiot saw them...
