Laboratory works:   Assembly language programming using 8085\8086\8088 trainer                                            kit. The programming should include: Arithmetic operation, base conversion, conditional branching etc. Sample Lab work list may include:
·         Assembly language program using 8085 microprocessor kit.
·         Program should comprise the use of all types of instructions and addressing modes.
·         The programming should include the concept of Arrays and the concept of Multiplications and Division operations on Microprocessor.
·         Assembly language programming, using any type of Assembler, which should include the different functions of Int 10h, and Int 21h.
