Data General Eclipse MV
From Computer History Wiki
The Eclipse MV was a family of supermini computers, created by Data General in competition with the DEC VAX family. It was backwards compatible with the earlier Eclipse family.
The first model in the family was the Eclipse MV/8000, code named Eagle. Its development was described in Tracy Kidder's book The Soul of a New Machine. According to the book, the Eagle started as a bit of a skunkworks project, with project Fountainhead being the company's official path to a new 32-bit architecture. However, Fountainhead failed to produce a viable product, so Data General had to fall back to the Eagle which ultimately had a moderate success on the market.
