The Architecture of the Lisa Personal Computer
Article Abstract:
Apple's Lisa Personal Computer was designed to be intuitive, consistent, integrated to perform to the way people work, high performance, to have an open architecture, and to be reliable. The Lisa uses an MC 68000 microprocessor to address 16 Mbytes using the Memory Management Unit. A high-resolution bit-mapped display allows virtually unlimited graphics and multiple texts fonts. The Lisa Operating System performs file management, process management, memory management, and event and exception handling to support the system's integrated software. Memory management is provided by the Lisa OS. The user interface is based on the Smalltalk system, with windowed graphics and icons manipulated by a single-button mouse to provide intuitive means for user-system interaction. A large library of software units to be used across all applications make for a consistent user interface. The Desktop Manager provides an iconic mechanism for creation and management of files or documents. Diagrams illustrate the graphics and window capabilities of the Lisa.

Space station data management system architecture
Article Abstract:
The Space Station Data Management System (DMS) consists of the hardware and software which support data processing, communications, and data storage of on-board systems. It also provides the operating environment and man-machine interface for operating and controlling orbiting systems. The development of the DMS is discussed, including the evolution of the requirements of the system, its features and functions, and the assessment of its architecture.
