One would assume it is part of a academic course where it is common to use cheap and freely available (often obsolete) components. Apart from knowing what an interface is and what 8279's and 8052's are, I am still confused as to OP query. The ol' simple plug-and-play interface is always the best!There is no interface. You connect the pins with the same name together. There is no real reason to use such a chip since it is an obsolete 40-pin gunboat whose functions can easily be accomplished with the microcontroller alone. Why would you want such a clunky solution?
