boa: [IBM] n. Any one of the fat cables that lurk under the
floor in a dinosaur pen. Possibly so called because they display
a ferocious life of their own when you try to lay them straight and
flat after they have been coiled for some time. It is rumored
within IBM that channel cables for the 370 are limited to 200 feet
because beyond that length the boas get dangerous -- and it is worth
noting that one of the major cable makers uses the trademark
`Anaconda'.
