8086 Microprocessor Trainer Kit

8086 microprocessor trainer 250x250

          The Intel 8086 is a 16-bit microprocessor intended to be used as the CPU in a Microcomputer. This is one step above 8085 (8-bit) microprocessor. The term '16-bit" means that its arithmetic logic unit, internal registers, and most of its instructions are designed to work with 16-bit binary words. The 8086 has a 16-bit data bus, so it can read data from or write data to memory and ports either 16 bits or 8 bits at a time. As its address bus is 20-bit wide, it can address memory upto 1,048,576 locations. Each of the 1 MB locations represents bite-wide. Therefore it is necessary to study by experimentation how an 8086 microprocessor responds for various conditions. Microprocessor trainer Model MPT-86, is an 8086 trainer. Using this trainer, students studying in, electronics, electrical, instrumentation, mechanical, chemical engineering subjects, B.Sc. (electronics, computers, and physics) laboratory, and polytechnics can learn programming an 8086 Microprocessor. This can be used to some extent for designing prototypes.
