Robert W. Doran · Computer · 1988
A description is given of extensions to the architecture of Amdahl's first mainframe computers, which were hard-wired implementations of the IBM System/370 architecture, and the why's and how's of their development are examined. The latest architecture helps maintain compatibility with a changing standard. Its multiple-domain facility allows multiple operating systems to share one mainframe system.>
