Project#1: GRAPHICS DISPLAY CONTROLLER

By: Troy Sparks and Mitch Lanz
Advisor:
Description: The Intel 82720 Graphics Display Controller is a faster graphics (controls pixels on the video terminal) controller.

Project #2: MEMORY MANAGEMENT UNIT FOR THE COMMODORE 64

By: Todd Corrigan, Roger Jackels, and Mark Wehlage
Advisor:
Description: To design and build a system resource manager for several microcomputers. A system resource manager is a computer used as a controller of a central memory. The goal of our design was to replace the local disk drives and eliminate the need for duplicate floppy disks in a multi-user environment.

Project #3: MICROCOMPUTER-BASED INTEGRATE CIRCUIT TESTER

By: Rex Kamhung Chow, Tom Oschwald, and Jeong Shin
Advisor: Dr. S. Lekhakul
Description: This project required hardware and software design for an integrated circuit tester to be operated in conjunction with a Sperry microcomputer. The software, written in the C language, was designed to detect logic gate failures in any of the 35 types of 7400-Series LSI integrated circuits. The microcomputer output indicated whether each IC tested was good or faulty.

Project #4: PART 1: LASER DIODE DRIVER RISE/FALL TIME STUDY
PART 2: ULTRA STABLE TEMPERATURE CONTROL

By: David J. Sternal and Scott A. Kohls
Advisor:
Description: To determine the rise/fall of the current output from a Sharp Model #IR3C01 laser diode driver integrated circuit. This information will then be used to determine how useful these IC's will be in sending high speed binary information via fiber optics.

Project #5 RMX OPERATING SYSTEM

By: Joel R. Goergen and Brian Fischer
Advisor: Dr. K. Miller
Description: The RMX Operating System is a real time, multi-tasking system capable of handling several operations. Basically, a system clock is used to generate and interrupt every so many milliseconds to instruct the processor to process the next task on the list. RMX uses a combination of priority (0-256, zero being the lowest), wait, sleep, and suspended states to decide which task shall be executing at any given instant.

Project #6 TOUCH TONE TO VOICE

By: Steve Albers, Phil Berling, and Paul Voit
Advisor:
Description: Goal is to develop a communication link between the phone lines and any host computer. This communication link will allow a person to call a host computer from any place via the phone lines and receive information that the person specifies by using touch-tones. The ultimate goal is to have the information requested sent over the phone lines by voice-synthesis.
