The short version

One of the model numbers the ND-500 architecture was sold under. Model numbers on this line indicate performance and user capacity, not different architectures - the underlying CPU is the ND-500/2 implementation. ND rated the range on its own ADP/OA scale, where an ND-100/CX is 1.0, and in Whetstone MIPS.
