IBM ® System/360 changed the IT industry forever, and it transformed how much of the world’s work gets done even today

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.
