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 :

1. Design student projects.
2. Familiarize components used in Microprocessor based instruments.
3. Study the signals generated by the Microprocessor.
4. Learn the art of programming in machine language.
5. Design application oriented equipment.
6. Design and debugging techniques, etc.
7. Perform input / output experiments.
8. Instruction set of 8085.
