This report provides a technical description and operating guidelines for the IMSAI 8080 microcomputer in the Department of Secondary Education at the University of Illinois. An overview of the microcomputer highlights the register array, address logic, arithmetic and logical unit, instruction register and control section, and the data bus buffer.…

Implementation of an ISA FORTRAN standard for executive functions and process input-output within a simulation system called MINIFOR provides a useful real-time program development tool for small single function, dedicated minicomputers having a FORTRAN compiler but limited program development aids. A FORTRAN-based pre-compiler is used off-line to…

Documentation of the Coursewriter II Function FCALC is provided. The function is designed for use on the IBM 1500 instructional system and has three major applications: 1) comparison of a numeric expression in buffer 5 with a numeric expression in buffer 0; 2) comparison of an algebraic expression in buffer 5 with an algebraic expression in buffer…

Longley proposed a set of data for use in testing regression programs. This paper shows that the numerically accurate solution is likely to be an unreasonable estimate of the regression coefficients for this problem. This is true because the accuracy of the data and appropriateness of the model may affect the solution more than the computational…

The Airman Training Line Simulator was designed as a managerial aid for investigating and evaluating the various and diverse policy interaction which impact on basic military training and entry-level technical training courses. The user's manual provides user-oriented documentation on the concepts and logic underlying the model. The presentation…

The goals of the Digital Systems Education Project (DISE) include the development and distribution of educational/instructional materials in the digital systems area. Toward that end, this document contains three reports: (1) A FORTRAN IV Design Program for Low-Pass Butterworth and Chebychev Digital Filters; (2) A FORTRAN IV Design Program for…

A Data Element Dictionary/Directory (DED/D) is a software tool that is used to control and manage data elements in a uniform manner. It can serve data base administrators, systems analysts, software designers, and programmers by providing a central repository for information about data resources across organization and application lines. This…

A computer program is described for identification of chiral centers in molecules. Essential input to the program includes both atomic and bonding information. The program does not require computer graphic input-output. (BB)

Since the service requirements of a utility depend on the distribution of population and land use in the service area, the planning for future requirements depends on accurate projections of future distributions. This systems approach model organizes land use data as an aid to facility planning. Included as variables are residential, commercial,…

The two purposes of this investigation were to study the effects of variance heterogeneity on three selected multiple comparison procedures and to determine if either of two nonstandard methods would be superior to the conventional methods based on mean square within. The three procedures studied were the Wholly Significant Difference Test (WSD),…

Interim work is documented describing efforts to modify computer techniques used to recognize and process English language requests to an instructional simulator. The conversion from a hand-coded to a table driven technique are described in detail. Other modifications to a simulation based computer assisted instruction program to allow a gaming…

This basic introduction to microcomputers provides the neophyte with the terminology, definitions, and concepts that explain the microcomputer and computing technology in general. Mathematical operations with binary numbers, computer storage, controlling logic, and the concepts of stack and interrupt are explained. (RAO)

The primary purpose of this project was to build a data base that would aid in identifying disadvantaged persons and later in identifying handicapped persons in the services areas of the Los Angeles Community College District. Five main steps were involved: (1) finding a machine readable file of all enrolled students in the District; (2) defining…

In this study the advantages and problems involved in using Generalized Data Management Systems (GDMS) to expand the capabilities of information retrieval (IR) systems are investigated. In particular, the design of a Data Manager-1 (DM-1) based system for the Reliability Analysis Center (RAC) at Griffiss AFB, Rome, New York is studied. A design…

A series of six functions and a station command have been designed to enable Coursewriter II authors to use the plotting capability of the IBM instructional system in presenting course material. This capability has been augmented to include the ability to graph mathematical functions or other data on the 1510 terminal. Documentation of the Plot…
