Supermini
From Computer History Wiki
A super minicomputer, or commonly just super-mini, is a category of small computers more powerful than a traditional minicomputer, but not as large or powerful as a mainframe. They were typically 32-bit computers. An early and very successful example is the VAX family.
The super-mini was obsoleted during the 1980s by smaller and faster microcomputer based machines, to great distress to manufacturers like Digital Equipment Corporation.
