PC/IX 1.00
Released in 1984 by IBM/Interactive Systems Corporation
For IBM PC XT model 5160
IBM Part number: 6428163

IBM Personal Computer Interactive Executive, or PC/IX, was an
unsuccessful single-user Unix port to the IBM PC XT based on System
III Unix. PC/IX was created by Interactive Systems Corporation and
sold through IBM.

Interactive Systems Corporation also later developed Advanced
Interactive Executive, (AIX)  based on UNIX System V for the RISC
based IBM 6150 RT.

However, the successors of PC/IX are 386/IX and Interactive Unix.

This software is designed to operate on an IBM PC XT model 5160. It
requires a hard drive, and may require a 100% XT hardware compatible
controller card. It also may not work with VGA.
