Circuits in SLT

The Solid Logic Technology by IBM was the first step to circuits in computers. So the whole concept of computers changed basically on April the 7th in 1964. This technology was published with the System/360. It was a hybrid technology with transistor-modules and other devices on a circuit board.
SLT was a revolutionary technology for the year 1964 with improvements compared to other manufacturing technologies and brought an enormous success to the IBM/360-mainframes during the 1960s. SLT replaced the SMS-Technology (Standard Modular System). Out of this operation later emerged the monolithic integrated circuits (Solid Logic Dense, Advanced Solid Logic Technology, Monolithic System Technology).
IBM produced hundred-million of SLT-modules in a highly automated, special built manufacturing plant in East Fishkill, NY.
