There have been several (at least two) ways of numbering products so there might be some overlap between lists. An early standard used two to four digit codes for product numbers. For example :
* [[ND 69]] a 64 kbyte cache memory for NORD-500
* [[ND 511]] a 10 Mbyte cartridge drive
* [[ND 1100/S]] a [[NORD-10/S]] BASIC system
For more see the list of [[List of 2 digit product codes|2 digit]], [[List of 3 digit product codes|3 digit]] and [[List of 4 digit product codes|4 digit]] product codes.
Later on it seems the product numbers were turned into six-digit codes, for example :
* [[ND 230210]] WinLink software
* [[ND 110017]] Magnetic Tape Driver
For more, see the [[List of 6 digit product codes]].

== NORD-1 Series Boards ==
(Main article [[NORD-1 boards]])
There is a lot of different boards used in the NORD-1 computer. Most are numbered with a three digit code starting at 101 and at least going up to 504. The NORD-1 was one of the first computers to be constructed of integrated circuits instead of transistors. Almost all of the boards are built with the 74-series IC:s.

This is an incomplete compilation of known hardware and systems that were developed by Norsk Data AS. The list contains both systems, boards and single items mentioned in documentation and other places. Links to online resources, references and to where hardware is located will also be included.

Testing electronics at CERN with a NORD-10.

There have been several (at least two) ways of numbering products so there might be some overlap between lists. An early standard used two to four digit codes for product numbers. For example :

For more see the list of 2 digit, 3 digit and 4 digit product codes.

Later on it seems the product numbers were turned into six-digit codes, for example :

For more, see the List of 6 digit product codes.

Systems

At the start of the PC revolution Norsk Data AS tried to keep up with the times and started to sell rebranded PC products. It also branched out into unix work stations like the Dolphin series ( might have been called Uniline in the beginning ).
