IBM System 360 circuitry in 1967 used Solid Logic Technology (SLT).
SLT used half-inch ceramic squares on which circuits were printed that connected
minute (see later) transistors, diodes, and resistors, all protected by an
aluminium cover. These multipronged square units were soldered on to printed
circuit cards, that in turn plugged in to back panels.
