1. IBM 709 A computer made by IBM oriented toward scientific work. The 709 had the same basic architecture as the IBM 704 but with many I/O and performance refinements over the 704. The IBM 709 like the 704 had 36-bit memory words, 15-bit addresses and instructions with one address. A few index register instructions had the infamous 15-bit decrement field in addition to the 15-bit address. The IBM 7090 was a transistorised version of the 709. [Difference between 704 and 709?]
