A correspondent from England tells us that one of ICL's most
talented systems designers used to be called out occasionally to
service machines which the field circus had given up on.
Since he knew the design inside out, he could often find faults
simply by listening to a quick outline of the symptoms. He used to
play on this by going to some site where the field circus had just
spent the last two weeks solid trying to find a fault, and
spreading a diagram of the system out on a table top. He'd then
shake some chicken bones and cast them over the diagram, peer at
the bones intently for a minute, and then tell them that a certain
module needed replacing. The system would start working again
immediately upon the replacement.
