jan 1, 1949 - Magnetic Core Memory

Description:

While working on the Whirlwind project at MIT, Jay Forrester writes a notebook entry on June 13 that describes his early thoughts on the “coincident current” technique for a magnetic core memory system. This system was the first reliable high-speed random access memory for computers. Magnetic core memory was widely used as the main memory technology for computers well into the 1970s.
