Description
Solid Logic Technology (SLT) module card. Rectangular black and brown perforated circuit board with three square modules soldered on to it. Two modules are white with small soldered tracks. One has silver IBM cap.
Brief History
Miniaturisation of components and storage devices as well as circuitry has been at the forefront of advances in computer technology since the early electro-mechanical computers.
Transistor technology, developed in the late 1940s, eventually reached a high level of miniaturisation along with significant performance and reliability advances. The equivalent of one pluggable card of transistors could now be housed in a module measuring one square centimetre, as seen in this Solid Logic Technology module card, introduced by IBM in 1964 with the IBM System/360 series and related machines. Performance improved so that two 10 digit numbers could be multiplied 400,000 times per second.
