Abstract :
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.<>
