8086 microprocessor trainer kit, Adikers Model: AZ239

Brand: Adikers
Model: AZ239

1. introduction
This system is the best supporting experimental equipment for teaching courses such as
"Microcomputer Control Technology" and "Sixteen-Bit Microcomputer Principles and
Interfaces". With the design concept of small system, multi-function and easy expansion, the
motherboard is mainly based on the experiments of "8086 Series Microcomputer Experiment
Guide", adding address bus, data bus, control bus lead-out and expansion unit (area), so that
the school can start from the needs , optional expansion modules provide a good experimental
development environment for teaching experiments, curriculum design, and graduation
projects in various colleges and universities.

i) There are two working modes: one is to run with a PC, and realize various debugging and
running operations while being online with the host software; the other is to run offline,
the experimental system comes with its own keyboard, display circuit and monitoring and
management program. In the absence of a PC, the experimental program can also be
debugged through memory reading and writing, single step, breakpoint, full speed and
other methods.
ii) Experimental openness: The experimental circuit unit should be as independent and open
as possible, such as an open keyboard, an open display, an open serial port, etc., to provide
the possibility to adapt to a variety of experiments.

iii)Necessary measuring instruments: Equipped with dual-channel virtual oscilloscope
measurement card.

2. System composition
