IBM 737 Magnetic Core Storage Unit

The IBM 737 was formally announced on October 1, 1954. Users of the IBM 701 Data Processing System could specify the 737 in lieu of the IBM 706 Electrostatic Storage Unit to gain the advantage of magnetic core storage, viz., the elimination of regeneration time and the reduction of processing time in many applications. For example, the 737 reduced the time needed to perform additions, including access, from 60 microseconds to 36 microseconds. This faster processing speed was especially beneficial in problems involving large amounts of logic.
