ND-500
From Wikipedia, the free encyclopedia
The ND-500 was a 32-bit superminicomputer delivered in 1981. It relied on a ND-100 to do housekeeping tasks and run the OS, SINTRAN III.
A configuration could feature up to four ND-500 CPUs, in a shared-memory configuration.

[edit] 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.
[edit] ND-500/1
Sold as the ND-500, ND-520, ND-540, and ND-560.
[edit] ND-500/2
Sold as the ND-570, ND-570/CX, and the ND-570/ACX.
