A Microcomputer Laboratory and Its Courses

A new microcomputer laboratory within the Department of Electrical and Computer Engineering at Clarkson College is described. The laboratory, while not changing the conceptual goals of the existing courses, has had a positive impact on these courses, particularly the introductory ones. The laboratory has made possible two new courses: a microcomputer course for all engineering and science students, and a project-oriented course for seniors in electrical and computer engineering. The course changes and new offerings are discussed and evaluated.     

An LSI-11 Microcomputer Laboratory

This paper summarizes the design, development, and implementation of an eight station microcomputer laboratory based on the DEC LSI-11 processor. The objectives and requirements of the facility are outlined as background for understanding the system design. Other sections are devoted to hardware, software, and courseware development for the laboratory. Hardware includes the LSI-11 processor, 16 channels of A-D input (eight channels differential), two channels of analog output, a minifloppy disk drive, a CRT terminal, and serial data links to an IBM 370 system. Software includes a custom-built monitor for the LSI-11, a cross assembler, simulator, linker, and down-line loader which run on the IBM 370, and special A-D and D-A routines. Courseware includes ten self-paced laboratory exercises, five real-time monitoring and control experiments, and a series of TV tape cassettes. Hardware plans, software listings, and class materials are available to interested readers by writing to the authors.

Microcomputer System Laboratory Course in a University Environment

A two-part microcomputer system laboratory course at the Technical University of Munich is presented. The course introduces the students into organization and programming of two basically different microcomputer systems which are based on a microprocessor with fixed instruction set (Intel 8080) and on a fast user-microprogrammable bit-slice microprocessor (Am 2900). Both systems are used in real-time projects. The 8080 system performs an experimental verification of the "inclined plane" problem and the 2900 system acts as a real-time balance for weighing the model of a railway wagon.

A Microcomputer Training Course

A major effort to upgrade training programs to include microcomputer concepts is becoming necessary in many government, industrial and educational institutions. Professional and technical staff who are familiar with conventional digital logic design need to learn new techniques and new technical jargon. This paper will describe training objectives which must be kept in mind when designing or evaluating microprocessor courses. These objectives include giving the student a detailed understanding of the operation of all elements in the basic CPU-memory-I/O microprocessor system configuration. The relationship between the hardware operation and the instruction set of the machine must be emphasized, and machine level programming must be understood. Laboratory exercises are suggested.     

A Microcomputer Interfacing Course

A hands-on undergraduate laboratory course is described in which microcomputer hardware and practical digital integrated circuit design are taught in a motivating and educationally efficient manner. Each student in the course is given the task of designing an interface between an Altair 8800 microcomputer and an input-output or memory device. As a result of two offerings of the course nine input-output devices and three memory types have been interfaced to the system. The educational advantages and the results achieved through this approach to microcomputer hardware education are discussed.
