I was a bit surprised to see that it used 2901 with a date code of 1985 -
the 2901 was introduced 10 years before.

In the late 1970s, Norsk Data implemented the ND10 architecture with the
2901. It was thought that this would give a modest uplift over the previous
generation, and the planned name was ND10S. It turned out to be so fast
that Norsk Data gave it the name ND100 instead :-)
