Discusses development of an analog simulation program for microcomputers similar to those available on mainframe computers. The program is interactive, more user-friendly than batch mode mainframe simulators in use, and has user help, error detection, and medium resolution graphics for presentation of system responses.

A brief package of subroutines (which can be typed in 15 minutes) enables a standard Apple II Plus, IIc, or IIe microcomputer to simulate a pen-plotter. Techniques for using this package in introductory engineering graphics courses are described. A sample program (which draws an oblique line) containing the subroutines is included. (Author/JN)

Describes a relatively inexpensive system which allows students in a digital control course hands-on experience in the implementation of control algorithms on a variety of processes. The system uses two computers, one for real time simulation of the process and the other for implementation of the digital control algorithms. (JN)

Presents algorithms for the simulation and motion display of the three basic kinematic devices: (1) four bar linkages; (2) the slider crank; and (3) the inverted slider crank mechanisms. The algorithms were implemented on a Commodore-VIC 20 microcomputer system with 6500 bytes of available memory. (Author/JN)

Demonstrating petroleum engineering concepts in undergraduate laboratories often requires expensive and time-consuming experiments. To eliminate these problems, a graphical simulation technique was developed for junior-level laboratories which illustrate vapor-liquid equilibrium and the use of mathematical modeling. A description of this…
