UNIVAC 9000 series information


Univac 9400 installation

The UNIVAC 9000 series (9200, 9300, 9400, 9700) is a discontinued line of computers introduced by Sperry Rand in the mid-1960s to compete with the low end of the IBM System/360 series. The 9200 and 9300 (which differ only in CPU speed) implement the same restricted 16-bit subset of the System/360 instruction set as the IBM 360/20,[1] while the UNIVAC 9400 implements a subset of the full 32-bit System/360 instruction set.[2] The 9400 was roughly equivalent to the IBM 360/30.

In 1972, UNIVAC stopped development of its 9000 series systems, in favor of hardware acquired from RCA, now called UNIVAC Series 90.
