Solid Logic Technology (SLT)

This substrate was then either encapsulated in plastic or covered with a metal lid to create a "Solid Logic Technology" (SLT) module.

IBM implemented its IBM Solid Logic Technology modules in hybrid circuits for the IBM System/360 in 1964.

IBM's System/370 follow-on to the System/360 used SSI ICs rather than Solid Logic Technology discrete-transistor modules.

Solid Logic Technology (SLT) was IBM's method for packaging electronic circuitry introduced in 1964 with the IBM System/360 series and related machines.

In 2002 he was made a Fellow of the Computer History Museum "for engineering management of the IBM Stretch supercomputer, and of the Solid Logic Technology used in the IBM System/360, which revolutionized the computer industry."
