The ND-5000 family is the third generations system based on the ND-500 architecture. It is a totally new construction both in hardware and physical layout. The ND-5000 CPU uses the same instructions as the ND-500 CPU but adds a couple of new instructions called '87 extensions', also found in the ND-500/1 and ND-500/2 CPUs.

The new ND-5000 CPU replaces 24 cards in the old ND-500 arcitecture. The single processor ND-5700 system have the same computational power as a ND-570 system.

The ND-5000 series of computers is able to run both SINTRAN III and NDIX, Norsk Data's version of UNIX.

Hardware implementation

The ND-5000 family systems uses a ND-100/ND-110/ND-120 CPU as I/O processor.

Models

The original series of ND-5000 computers came in three different models, ND-5700, ND-5800 and ND-5900. Later additions to the family were Compact models, ND-5200 Compact and ND-5700 Compact[1].
