Section of a computer memory card, Monolithic System Technology (MST). Black rectangular card with copper tracks, multiple square solder points in grid layout. Contains 4 rectangular components, one with pins only remaining.
Brief History
Monolithic System Technology (MST) was introduced by IBM in 1968, first appearing in the System/370 and replacing Solid Logic Technology (SLT).
With the improvement of integrated circuits more and more circuit functions were able to be housed in each module, thus reducing the number of cards required in a computer. MST replaced discrete transistors and diodes with monolithic integrated circuits. The interconnecting circuits of the boards that these cards plug into were now very fine printer circuits. The multiplication of two 10 digit numbers could now be done over 1,000,000 times per second.
