'''NDIX''' is the name of the Norsk Data port of BSD unix to the [[ND-500 family|ND-500]] and [[ND-5000 family|ND-5000]] hardware. The OS runs on the ND-500(0) CPU and uses the ND-100 part of the machine as an I/O processor. 
The ND-100 CPU runs [[SINTRAN III]] and communicates via [[XMSG]] with NDIX, but compared to how the interaction between the ND-100 and ND-500(0) works when running Sintran it is quite different for NDIX. 
In the Sintran world the ND-100 launches different processes on the ND-500(0) and mage them from the ND-100. In the NDIX world it works in the opposite way; all process management is on the ND-500(0) (NDIX "owns" the ND-500(0)) and the ND-100 is only used as an I/O processor. This is achieved by using a special NDIX microcode on the ND-500(0) and a specially generated Sintran for the ND-100.

NDIX was an effort to gain market shares on the emerging UNIX market for servers. The last version of the BSD-based version of NDIX (NDIX-C) was released in 1989, and since the development of the ND line of hardware ended so did NDIX. 
Note that there was a software called NDIX-V that did run on the 88k machines ND sold. This was just System-V for 88k and nothing ND-specific about it.

== Hardware requirement ==
; NDIX-A and NDIX-B (4.2BSD-based) only run on ND-500. :
* ND-500/CX (second generation, MPM 5 and 500/2)
* 2-6 MByte private memory for the ND-100 CPU
* Up to 32 MByte shared memory

; NDIX-C (4.3BSD-based) only runs on ND-5000. :
* ND-5400, ND-5500, ND-5700 or ND-5800.
* 32-bit ND-120 CPU.
* 2-6 MByte private memory for the ND-100 CPU
* Up to 32 MByte shared memory

== History ==
The beginning of NDIX started at at Luleå Tekniska Högskola (LuTH) (now Luleå University, www.ltu.se) were a C compiler (LCC, the Lulea C Compiler) was written for ND-500.
This did draw quite some interest from ND, so people from ND Service Team were stationed at LuTH working with porting 4.2BSD to ND-500.
The resulting operating system were called NDIX-A. It was used only internally and at LuTH.

ND Service Team continued development of NDIX, mostly focusing on modifying Sintran and the ND-500 microcode to better work together with NDIX. Also a better compiler were added to the system, a port of the Portable C Compiler for the system. This version was released as NDIX-B.

The last version of NDIX, the NDIX-C version, was a port of 4.3BSD and was released not long after NDIX-B. It was ported by Norsk Data LTD, Benham Valence, Newbury, Berkshire, England and did only run on the ND-5000 machines. NDIX-C became widely used, mostly at universities and research facilities.

== Software requirement ==
Besides the software for NDIX itself, there were a need for a special version of Sintran itself.
* NDIX-B needs Sintran K/VSX Workmode 300.
* NDIX-C needs Sintran K/VSX Workmode 600 (or later). Latest release was Workmode 602.

Also, a special microcode for the ND-500(0) adapted for NDIX was needed.
