What Happened on January 9th

Erich Bloch, a member of the team that engineered IBM's System/360 family of computers, is born. In 1962, IBM chose Bloch to head its Solid Logic Technology (SLT) program--an alternative technology to integrated circuits (ICs) which, at that time, had not yet been successfully mass produced. SLT was the electronics technology behind the System/360, a family of six mutually compatible computers and forty peripherals that could work together and which provided forward and backward software and hardware compatibility across the family.
