SINIX is a discontinued variant of the Unix operating system from Siemens Nixdorf Informationssysteme. SINIX supersedes SIRM OS and Pyramid Technology's DC/OSx. Following X/Open's acceptance that its requirements for the use of the UNIX trademark were met, version 5.44 and subsequent releases were published as Reliant UNIX by Fujitsu Siemens Computers.

Features[edit]

In some versions of SINIX (5.2x) the user could emulate the behaviour of a number of different versions of Unix (known as universes). These included System V.3, System III or BSD. Each universe had its own command set, libraries and header files.

Xenix-based SINIX[edit]

The original SINIX was a modified version of Xenix and ran on Intel 80186 processors. For some years Siemens used the NSC-32x32 (up to Sinix 5.2x) and Intel 80486 CPUs (Sinix 5.4x - non MIPS) in their MX-Series.

System V-based SINIX[edit]

Later versions of SINIX based on System V were designed for the:

  • SNI RM-200, RM-300, RM-400 and RM-600 servers running on the MIPS processor (SINIX-N, SINIX-O, SINIX-P, SINIX-Y)
  • SNI PC-MX2, MX300-05/-10/-15/-30, Siemens MX500-75/-85 running NS320xx (SINIX-H)
  • PC-MXi, MX300-45 on the Intel X86 processor (SINIX-L)
  • SNI WX-200 and other IBM-compatible i386 PCs on the Intel 80386 and newer processors (SINIX-Z)


The last release under the SINIX name was version 5.43 in 1995.

Reliant UNIX[edit]

The last Reliant UNIX versions were registered as UNIX 95 compliant (XPG4 hard branding).

The last release of Reliant UNIX was version 5.45.
