Discusses topics involved in the selection of an analog-to-digital (ADC) converter and associated front-end signal conditioning hardware. Reviews what types of ADC's are available, best type for particular application, conversion rates, amplification, filtering, noise, and compatibility issues. Suggests purchase strategy and supplies names and…

Describes a microcomputer-based multichannel analyzer (MCA) in which the front end is connected to a microcomputer through a custom interface. Thus an MCA System of 1024 channel resolution, programmable in Basic rather than in machine language and having moderate cost, is achieved. (Author/SK)

The Apple game port has two types of inputs: the paddle input and the button input. Scientific applications of these input-output units are discussed, examining analog inputs (potentiometers, thermistors, and photoresistors), single bit digital inputs, and single-bit outputs. (JN)

Offers rationale for and a description of a microprocessor-based control system project for mechanical engineering students. Includes reasons for selecting a Texas Instruments TM990/189 microprocessor system. (SK)

Presents information on interfacing microcomputers for scientific users of S-100, TRS-80, PET, and Apple microcomputers, including device-select pulses, programing considerations, data input, data output, and power supplies. (JN)

Discusses the physics of liquid crystal displays (LCD) which is based on polarizing properties of crystals controlled by electric command. Production of alphanumerics, display control, and input are considered. (JM)

Briefly describes an 8085-based controller for use with the Burroughs Self-Scan display, including display and editor hardware and software and the 126-item program. (SK)

Microprocessor-based student experiments are described, including flowcharts of a typical program for time interval measurement and experimental and measurement subroutines. (JN)

Surveys trends in hardware (logic, memory, storage) input-output technology, software, computer architecture and organization, communications, and artificial intelligence. (JN)

Discusses how the British Post Office is using the Prestel information retrieval system. The information structure adopted for the Prestel databases and how the Prestel system hardware works are presented. Computer system software, types of information, and the impact of Prestel system on society are also presented. (HM)

Describes the use of microcomputers in data acquisition and simulation of physical phenomena. Discusses digital and analog inputs/outputs, simulations, and interactive programs in mechanics. Includes examples of computer programs. (SK)

Discusses single-board microcomputers which are designed primarily for data acquisition and control. Directed toward individuals with little or no hands-on experience with microcomputers, this article gives references, among others, for reading about and purchasing microcomputers. (SK)

Describes a procedure for determining the coefficient of restitution using a microcomputer which collects and sends data to a large computer where analysis is done and graphical output is generated. The data collection hardware and software are described, and results are illustrated. (Author/SK)

Describes how the graphics capabilities of the Apple Macintosh computer can be used in geological teaching by customizing fill patterns with lithologic symbols. Presents two methods for doing this: creating a dummy document, or by changing the pattern resource resident in the operating system. Special symbols can also replace fonts. (TW)

Presents examples of didactic computer software developed in a college of engineering, along with a discussion of pedagogical and systems considerations. Discusses the use of the computer in relation to Bloom's Taxonomy. Describes the system approach, which is used to sequentially develop valid and relevant software. (TW)
