INTERACTIVE Systems Corporation
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. ISC also partnered with
Segue Software and
Peter Norton Computing to develop 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.
