8085 Microprocessor Educational Lab Description and Specifications for Lab Tenders
8085 Microprocessor Educational Lab.
8085 Microprocessor Educational Lab Trainer - 8085 Microprocessor
Trainer can interface with IBM PC/XT/AT computer with the help of 96 bit
TTL I/O Experimental Interface and Editor Assembler Software. It is
quite an efficient system based on Industry Standard Intel 8085 ìp for
the purpose of training and prototype development of microprocessor
based systems. Its hardware is capable of supporting multi processor
configuration also.
The unit is self contained and requires no other apparatus. Practical
experience on this board carries great educative value for Science and
Engineering Students.
The Microprocessor trainer is designed to teach the subject of
Microprocessor programming and interfacing through practical,
essentially designed to teach the study of :
Design student projects
Familiarize components used in Microprocessor based instruments
Study the signals generated by the Microprocessor
Learn the art of programming in machine language
Design application oriented equipment
Design and debugging techniques, etc.
Perform input / output experiments
