INTERACTIVE Systems Corporation
From Wikipedia, the free encyclopedia
INTERACTIVE Systems Corporation (ISC) was a software company, known for their versions of the Unix operating system.
In 1977, ISC was the first commercial Unix vendor, selling IS/1, a Version 6 Unix variant enhanced for office automation which ran on most PDP-11's.. The later IS/3 and IS/5 were enhanced versions of System III and System V for PDP-11 and VAX.
ISC got especially well known for their Unix ports to the IBM PC. The first of these was a variant of System III, developed under contract to IBM, and known as PC/IX (Personal Computer Interactive eXecutive). Later ISC releases were branded 386/ix and finally INTERACTIVE UNIX System V/386 (based on System V Release 3.2). ISC was AT&T's official "Principal Publisher" for System V.4 on the Intel platform. [1]
ISC was also involved in the development of VM/IX (Unix as a guest OS in VM/CMS), IX/360 (native Unix on the System/360) and AIX, again under contract to IBM. It also developed and sold the Unix version of the Norton Utilities.
On September 26, 1991 Sun Microsystems and Eastman Kodak Company announced that Sun acquired the Intel-UNIX operating system business from ISC.[2] Final support for Interactive System V/386 from Sun ended on July 23, 2006.
