As a result of rapidly increasing interest in the UCSD PASCAL Software System, the Institute for Information Systems will establish an exchange service for software developed by users of the system. In addition to handling contributed programs, the exchange will function as a marketplace wherein authors of applications software packages, or computer based course materials, may sell their products to customers in return for royalty payments. The exchange will recover its operating costs through customer payments of small distribution charges, and will operate as a non profit public service.

This article discusses usability, performance, and management of minicomputer timesharing systems. It attempts to define the factors that make operating-systems usable and suggests ways in improving the usability and performance of application programs. While some parts of the discussion are specific to Digital's RSTS/E operating system, much should prove applicable to other systems.This article is based on a talk given at the Fall 1977 DECUS Seminar which will be published in the DECUS proceedings. Some material has been added, and a few items that are of interest only to RSTS/E installations have been removed.

This article presents some of the material that was included in a presentation by the author during the Spring, 1978 DECUS Seminar. Although it pertains most directly to PDP-11 computer systems using the RSTS/E Operating System, most of the concepts are applicable to the general problem of evaluating the performance of mini-computer timesharing systems. In discussing performance evaluation the article also details the tools available for evaluating this particular minicomputer timesharing environment.The information presented in this article is believed to be accurate, but no representation is made as to its particular accuracy or use, nor is any support for the features or software mentioned provided by Digital Equipment Corporation, Data Processing Design, Inc., or the author.

Attached Processing, an innovative concept in business data processing demanding novel computer systems architecture, divides computing into three broadly specialized functions: applications processing, data storage and management, and communications. In its realization, the Attached Resource Computer, communications are handled by combining hardware and software in a high-speed, short-range interprocessor bus managed by bipolar microprocessors; data storage and management is the province of dedicated small processors attached to the interprocessor bus through the bipolar microprocessors; applications processing is done in other small processors similarly attached but entirely unburdened by communication processing requirements. The system is capable of indefinite extension and essentially unlimited throughput at very modest cost.

A survey of minicomputer data base management systems was conducted to determine the current state of the industry. The results of the survey are highlighted in this paper to provide a broad view of the features of commercially available mini-data base systems. Among the topics presented are hardware requirements, software implementation, data independence, binding, integrity, privacy controls, installation base, availability, and user considerations. In addition, the relationship between the growth of the minicomputer market and mini-DBMS market in the second half of the 70's is emphasized.

The advent of low cost minicomputers and peripherals supported by extensive high level software in the late 1960's led to the possibility of dispersing computer power from isolated central sites to user sites. The experience of one of a group of six such sites in an academic environment is described. The experience gained can provide a guide to others attempting to produce similar installations on optimizing the choice of hardware and software.

UCSD PASCAL is a complete interactive software system for small computers, yet it offers many features normally found only on medium and large scale machines. It is designed to operate, with minimal adaptation, on most micro or mini computers based on 8-bit bytes and/or 16-bit words. Supported versions are available for use on machines based on the Digital Equipment LSI-11 or other PDP-11 processors, and on the 8080 and Z80 microprocessors. Having first been sent to users in August, 1977, the system is now in use on approximately 60 mainframes using these processors, and the list of users has started to grow rapidly.
