1. obs. Once upon a time, before all-digital switches made it possible
for the phone companies to move them out of the audible range, one could
actually hear the switching tones used to route long-distance calls.
Early {phreaker}s built devices called `blue boxes' that could reproduce
these tones, which could be used to commandeer portions of the phone network.
(This was not as hard as it may sound; one early phreak acquired the sobriquet
`Captain Crunch' after he proved that he could generate switching tones
with a plastic whistle pulled out of a box of Captain Crunch cereal!) 2.
n. An {IBM} machine, especially a large (non-PC) one.
