To satisfy the upgrading need in MTS-88.C teaching and developing. The 9 optional I/O boards give detailed information on the circuit operation including full circuit diagrams, theories, system flow charts, timing diagrams, input / output address, and also the needs of program & parts listing. Thanks to all of those MTS-88.C I/O board which are providing a total solution to the teaching and developing for knowing an idea about the 8088 microprocessor chip and its applications. Go with the MTS-88.C and its 9 I/O boards covered 35 experiments, you will find all the experiments are so simple and easy to be completed.
