The Solid Logic Technology (SLT), introduced
in 1964 by IBM in System/360, was the industry's
first high-volume, automatic, microminiature production
of semiconductor circuits. Mounted on 1/2-inch-square
ceramic modules seen here, the SLT circuits were
denser, faster and required less power than the
previous generation of transistor technology. (VV3081)
