Sinix is a Unix descendant developed by Siemens in 1984 and the predecessor of ReliantUnix . Originally presented by Siemens as a pure PC Unix for Intel 8086 CPUs in 1984 (as Xenix license / System III ), Siemens Nixdorf later increasingly developed the system as a server operating system, the last 32-bit version under the name Sinix was released in 1995 with version number 5.43, subsequent versions only appeared as ReliantUnix. The versions 5.4x corresponded to the guidelines laid down in the X / Open Portability Guide of July 4, 1995.
Special properties
The concept of the so-called universes used from version 2 (for PC-MX / NS32032) was unusual and unique . By entering a command, the user could choose between different Unix dialects:
- it was the "Siemens house dialect" and System III based.
- ucb corresponded to a 4.x BSD .
- att or xopen corresponded to AT&T SVR3.
Each of these universes had its own commands, headers, and libraries.
Sinix for Siemens PC
Sinix is the name of the Siemens version of the software product XENIX, which originated from the UNIX System III under license from AT&T.
- Versions
- 1984: Sinix Version 1.0 (for PC-MX and PC-X)
- 1986: Sinix Version 2.0 (for PC-MX2 / 4)
In the meantime, Sinix-Z is a version for standard PCs with Intel 80386 or Intel 80486 processors. The further development was stopped in 1990 in favor of the use of SCO UNIX .
Platforms
Originally developed for the multi-user system PC-MX / 9780 (Intel Multibus computer with 8086) and extended to the workstation PC-X / 9781 ( 80186 based), versions for PC-MX2 / 4 (CPU: National Semiconductor NS320xx ) and MX300 were later added / 500 (NS32032, NS32332 and NS32532) ported. The MX 300i and 500i were again ported back to Intel 486 and Pentium. With the change to the MIPS- based RM series, another porting took place.
