Almost :-)
The NORD-10/S was a NORD-10 plus caching and paging, while the
bitsliced version was to be called NORD-10/M (M for 'micro'), and was
so fast that it was renamed NORD-100, which was shortened to ND-100
later that same year (1978 - but the machine itself was released in
1979, so it was always sold as just ND-100).
