By the early-1980s, the information processing
power of electronic computers of the 1960s could
be held in one hand. The logic module used in the
large IBM 3081 system, introduced in 1980, was part
of the industry's densest circuit packaging technology.
Up to 133 electronic chips mounted in each module
(shown above) contained a total of 45,000 logic
circuits, as well as other circuitry. (VV3121)
