Laboratory Works:

The laboratory work includes Assembly language programming using 8085/8086/8088 trainer kit. The programming should include: Arithmetic operation, base conversion, conditional branching etc. The lab work list may include following concepts:

1. Assembly language program using 8085 microprocessor kit.

2. Use of all types of instructions and addressing modes.

3. Arrays and the concept of Multiplications and Division operations on Microprocessor.

4. Assembly language programming, using any types of Assembler, including the different functions of Int 10h, and 12h
