VISOR (Variable Interval Schedule Of Reinforcement) System Documentation

This program will be used in operant behavior research to monitor and record responses and trigger and record reinforcements on a variable reinforcement (VI) schedule. The original application of this program will be the servicing of several rat cages simultaneously. The response will be the pressing of a metal bar in the cage, the reinforcement will be the triggering of a feeding mechanism which disperses a food pellet into the cage. The subsequent applications of this program are not limited, in that the actual response and reinforcement devices and the subject type are all treated indifferently by the program.

Machine Recognition of Hand-Send Morse Code Using the M6800 Microcomputer (open access)

Machine Recognition of Hand-Send Morse Code Using the M6800 Microcomputer

This research is the result of an effort to provide real-time machine recognition of hand-send Morse code through the use of the M6800 microcomputer. While the capability to recognize hand-send Morse code messages by machine has been demonstrated before on large scale special purpose computers, on minicomputers, and even on the M6800 microcomputer, the main contribution of this paper is to demonstrate it with relatively understandable hardware and software.

Notes on the SWTPC MP-N Calculator Interface and the Calc-1 Program

This interface was bought to perform floating-point arithmetic and for its function capabilities such as SIN, COS, and e^x. My application required an integer truncation function that is not performed by this calculator, so i wrote a small assembly language subroutine to do it. A potentially irritating problem is that the calculator chip does not automatically convert to scientific notation if the numbers become too big to display in floating point. The control program must keep track of the display mode.

The NTSU School of Music Practice Room Scheduling System (open access)

The NTSU School of Music Practice Room Scheduling System

This is a report concerning the project I completed for my 590 (special problem) credit. The subject of this project was a system for interactive practice room scheduling by music students at NTSU. This system was created in the fall semester of 1982 as a class project for software Development (CSCI 553) with Dr. Irby. The system was not completely finished, and I received permission from Dr. Irby to finish it and help implement its use at the Music department. I was able to observe three usages of the system: Spring, Summer I, and Summer II semesters of 1983. This report details the problems encountered during each of these usages, and changes made to the system due to them. Results of a first-use survey, under documentation, and complete final code listings were also included.
