Mainframe Family

A large-scale computer architecture sold and supported as a whole product line or family of compatible models, rather than a single one-off machine. Belongs here: IBM System/360, the atlas's sole mainframe-family entity and the architecture that established binary compatibility across a whole model range. Does not belong here: a single early commercial machine sold without a compatible model family around it, filed under Commercial Computer.
