Midrange

Midrange is a generic term referring to a family of IBM mini-computers.

Systems that are in that family include:

Also see Wikopedia [category on Mini Computers http://en.wikipedia.org/wiki/Category:Minicomputers] which was a terminology that pre-dated Midrange, which came to mean bigger than a Mini but smaller than a Main Frame.
