<computer> 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.
