The ND-500 is a 32-bit superminicomputer delivered in 1981 by Norsk Data. It relied on a ND-100 to do housekeeping tasks and run the operating system, SINTRAN III.

A configuration could feature up to four ND-500 CPUs, in a shared-memory configuration.

Hardware implementations

The ND-500 architecture lived through four distinct implementations. Each implementation was sold under a variety of different model numbers.

ND also sold multiprocessor configurations, naming them ND-580/n and an ND-590n, where n represented the number of CPUs in a given configuration, 2, 3, or 4.

ND-500/1

Sold as the ND-520, ND-540, and ND-560.

ND-500/2

Sold as the ND-510, ND-530, ND-550, ND-560, ND-570 (and various /CX variants as newer ND-1x0 variants became available)

ND-505

A 31-bit version of the ND-500 machine, but . Pin 27 was snipped on the backplane, removing its status as a superminicomputer, allowing it to legally pass through the CoCom embargo. Cocom (Coordinating Committee for Multilateral Export Controls) was an embargo on Western exports to East Bloc countries during the Cold War [1], [2] The ND-505(/CX) uses a 500/2 CPU. 29 bits of addressing space is available for the user [3] (exactly how this relates to the physical 31 bits is not entirely clear).

ND-5000

The ND-5000 series was the latest physical implementation of the ND-500 architecture.


Cost

The price of the smallest ND-500 system in 1981 was 400.000 German mark, according to a 1981 article in Computerwoche (the source has since disappeared from the internet).
