			== 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.

	== ~~NDIX development centers~~ ==		== History ==
	~~There~~ were at ~~least one center~~ working on the NDIX system.		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.
	* Norsk Data LTD, Benham Valence, Newbury, Berkshire, England.		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.
	* Rumored that there was a center in Luleå Tekniska Högskola, ~~Luleå, Sweden~~.		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 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.<br>
			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.<br>
			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.
