The Eclipse MV/8000 was a 32-bit minicomputer produced by Data General during the 1980s. Codenamed Eagle during development, its architecture was a 32-bit extension of the previous 16-bit Eclipse series. The development of the computer and the people who worked on it were the subject of Tracy Kidder's book The Soul of a New Machine. The MV/8000 was succeeded by the MV/8000-II, MV/2000, MV/2500, MV/4000, MV/10000, MV15000, MV/20000, MV/30000 and MV/40000. Later models such as the MV/40000 were SMP systems with hot-swappable components.
The Eclipse MV was a 32-bit CISC architecture with a 4GB address space. The 4GB address space was divided into eight rings of 512MB each with a privilege mechanism mapped onto the rings. The outermost ring, ring-7, was the least privileged. The inner-most ring, ring-0 was the most privileged.
