EB-152 Introduction to Microprocessors 2
The EB-152 is a single board comprehensive instructional module
designed to teach advanced concepts of microprocessors to technology
students. The module can be operated as a stand-alone unit or integrated
to the newly developed EB-2000 Computer Managed Laboratory. The
module contains experimental circuits with which the student performs
a number of conceptual experiments at various levels of difficulty.
Manual or computer driver fault-finding exercises and testing are
available when the module is interconnected to the SB- 2000 system,
providing valuable experience in the training and diagnosis of faults.
Test equipment, when used, attaches to the board via 2mm jacks,
placed at various points around the circuits. Students are required
to do only a minimal amount of wiring so training time is maximised.
A comprehensive student manual is provided with each training module.
The manua1 correlates to the exercises to convey concepts relating
to the technologies covered, allowing focus on specific performance
objectives.
DESCRIPTION
The EB-152 module is designed so students will spend the maximum
time on the experiments and practice drills for testing comprehension
and troubleshooting. The module also ensures that students use their
time more efficiently. The printed circuit boards are pre-wired
so that set-up time is minimal. For operation the module is connected
to a PUZ-2000. To facilitate the exercises, all the major signals
are brought out on-board with 2mm jacks for tests and interconnections.
The ICs and the transistors are mounted on sockets, enabling easy
replacement. The student has only to plug-in the appropriate patching
cords and shorting plugs in order to perform the recommended experiments.
The boards also come equipped with "black boxes" containing
components used in the fault-finding and practice modes, components
that should not be visually identified by the trainee.
