The ability of a microcomputer to execute several programs at the same time is called "multitasking." The nature and use of one multitasking operating system Concurrent PC-DOS from Digital Research (the developers of the CP/M operating system) are discussed. (JN)

Discusses the brief history of microcomputers, offering some predictions about hardware trends. Gives explicit criteria for judging a computer language and discusses different programing languages in terms of what has been used in the past, and why, and what might be appropriate for the future. (JN)

Described is a variety of uses of the microcomputer when coupled with software available for systems using 6502 microprocessors. Included are several computer programs which exhibit some of the possibilities for programing the 6502 microprocessors. (DS)

The declining cost of hardware and the growing availability of supporting accessories (peripherals) have contributed to growth in the use of computers in chemistry. Examples of such uses are provided. (JN)

Discusses what to look for when considering the purchase of a microcomputer. Also discusses the basic features of word processing, spreadsheet, and database software. (JN)

Describes nature and installation of the QUADLINK board which allows Apple software to be run on IBM PC microcomputers. Although programs tested ran without problems, users should test their own programs since there are some copy protection schemes that can baffle the board. (JN)

Provides instructions for "seeding" the random number generator (RND) in Apple computer programs. If RND is not seeded, students would see the same examples, questions, graphics features, or other information each time they turn on the microcomputer and run a program. (JN)

Describes a program which simulates the kinetic behavior of a "typical" enzyme. Program objectives, background to the kinetic model used in the simulation, major program features, typical results obtained, and a note on the availability of the program (written in BASIC for Commodore microcomputer) are included. (JN)

Discusses using an Apple II microcomputer as a Laboratory Data System (LDS) for the analysis of data fed from a UV-Visible Spectrophotometer. (SK)

Describes an undergraduate laboratory project that combines microprocessor programing, interfacing, and system design to produce an inexpensive multichannel analyzer. (Author/CS)

Compares Apple Macintosh and IBM PC microcomputers in terms of their usefulness in the laboratory. No attempt is made to equalize the two computer systems since they represent opposite ends of the computer spectrum. Indicates that the IBM PC is the most useful general-purpose personal computer for laboratory applications. (JN)

Describes a college-level physics course which focuses on both physics knowledge/skills and use of microcomputers. Types of experiments done with the computers and how students use the computers to treat data are considered. (JN)

Describes a computer program which plots electric field line plots. Includes program listing, sample diagrams produced on a BBC model B microcomputer (which could be produced on other microcomputers by modifying the program), and a discussion of the properties of field lines. (JN)

Discusses a simulation on enzyme kinetics based upon the ability of computers to generate random numbers. The program includes: (1) enzyme catalysis in a restricted two-dimensional grid; (2) visual representation of catalysis; and (3) storage and manipulation of data. Suggested applications and conclusions are also discussed. (DH)
