Presents a system model for transmission of input data that is coming from terminals of users in a limited user resource-sharing environment. Performance of a mini/microcomputer receiving mixture of picture-phone terminal data is analyzed with constant service times, synchronous transmission, and single-server interruptions through first-order…

Briefly discusses the functions of microcomputer storage devices, printers, plotters, modems, speech devices, light pens, and touch panels. Capabilities of peripherals in various price ranges are compared to assist the personal computer owner in selecting devices appropriate to his needs. (MBR)

This hardware review describes such innovative features of the Texas Instrument Portable Professional Computer as integrated color screen and option slots permitting customization as well as the physical unit (inside and out), its mass storage flexibility, and sturdiness. A comparison with the IBM PC Portable is included. (MBR)

Describes and evaluates the hardware, software, peripheral devices, performance capabilities, and programing capacity of the Sinclair ZX Spectrum microcomputer. The computer's display system, its version of the BASIC programing language, its graphics capabilities, and the unique features of its data entry keyboard are discussed. (JL)

Briefly reviews the origins of the hypermedia concept, comments on its use in higher education, and describes a project at Dartmouth College that developed a training process to introduce a hypermedia authoring environment to the academic community. (CLB)

Describes a videodisc-based information display system in which a computer terminal is used to search the online PATSEARCH database from a remote host with local microcomputer control to select and display drawings from the retrieved records. System features and system components are discussed and criteria for system evaluation are presented.…

Outlines and analyzes new trends and developments at the Association for Information and Image Management's 1990 spring conference. The growth of imaging and the optical storage industry is emphasized, and new developments that are discussed include hardware; optical disk drives; jukeboxes; local area networks (LANs); bar codes; image displays;…

Presents the options and limitations available in microcomputer-based graphic systems. Factors that must be considered when selecting a system--resolution, color, video-compatibility, and cost--and the relationship between these factors are discussed. (MBR)

Reviews attributes of laser discs and "traditional" objections to use of audiovisual materials. Use of authoring systems as means of tailoring laser disc programs and updating aging materials is described. Flexibility and power of the Video Nova Authoring System is explained and illustrated and the SONY SMC-70 microcomputer is evaluated.…
