The CIAs were the bane of my Amiga-experience. Owing to somewhat careless use of a printer switchbox, I fried them twice in succession on the A500, and managed to destroy both chips on the A4000 by moving the computer about on my table so much that the modem cable worked itself lose. The stupidest thing I did was fry a 2.04 ROM. The pins on those chips are very sturdy, and require some pressure to be positioned over the holes in the socket. I didn't want to use my fingers, and needed something which would bend a lot of them at the same time. So I used an elongated plastic money chip---the kind you use in poker or roulette. Of course, those things are loaded with static electricity...
