IBM 7302 Core Storage

The IBM 7302 Core Storage unit was designed in 1957-1958 for the IBM 7030 (Stretch). The IBM 7030 could use from one to sixteen IBM 7302s (typically six); either individually or in interleaved groups of two or four. The IBM 7090 also used one IBM 7302. The IBM 7094 used one IBM 7302A. The IBM 7094 II used one IBM 7302, but it was a new model unique to the IBM 7094 II. The IBM 7080 also used one decimal model IBM 7302 with a different core stack than used in the binary models.
