Yes. The control board in my Dad's garage door
opener was killed by a close
lightning strike. My sister, who owns the house next door to him, lost the
motherboard on her PC -- and it wasn't on at the time, just plugged in.
I've seen ISA based internal modems that took surges from
strikes on the line. Some of them looked like they caught fire or at
least got very hot.
