The chief architect for IBM's computer AS/400, driven by the new Power PC RISC processors, reviews its design, architecture, and history, and some of the people behind its development. Different aspects will interest customers and application developers, but all chapters assume a general rather than specialized knowledge of computers. The machine interface, objects and object management, the integrated database, security and authorization, single-level store, and client/server computing are among the topics. No bibliography.
