A time sharing system embedded within the standard batch processing system for the CDC 6600 is described. The system is general purpose ond file-bosed, providing focilities for file input, manipulation, editing, compilotion, and conversational execution. It uses a simple scheme for system extension for a machine v/ith only one relocation and memory bound register. No attempt was made to use reentrant code, or to simulate segmentation or paging. Implementation time wos approximately six man-years, with the majority of the code being written in FORTRAN.

An I/0 system has been implemented in the Multics system that facilitates dynamic switching of I/0 devices. This switching is accomplished by providing a general interface for all I/O devices that allows all equivalent operations on different devices to be expressed in the same way.Also particular devices are referenced by symbolic names and the binding of names to devices can be dynamically modified.Available I/0 operations range from a set of basic I/0 calls that require almost no knowledge of the I/O System or the I/0 device being used to fully general calls that permit one to take full advantage of all features of an I/O device but require considerable knowledge of the I/0 System and the device.The I/O System is described and some popular applications of it, illustrating these features, are presented.

Methods for supplying medical personnel, especially in isolated areas, with the same sophisticated medical information and computational facilities that are available in major medical centers, were investigated. Inexpensive, readily available input/output terminals, including the pushbutton telephone, were tested with several biomedical application programs. An experimental network, consisting of several independent commercial time-sharing computers linked to user terminals through a small communication control computer, was constructed to demonstrate an efficient and flexible approach to remote computer access. The communication control computer, acting as a message handling and translating interface, allowed the use of a uniform terminal control language and common data handling conventions. By linking to the most powerful commercial time-sharing systems available, a reliable medical data processing network was established without a major investment in computer hardware or system software. This experimental work is a major part of the Medical Information Telecommunication Project in the Division of Computer Research and Technology (DCRT) at the National Institutes of Health (NIH).
