Implementation of Parallel Interface for Microprocessor Trainer

In this paper, parallel interface for microprocessor trainer was implemented. A programmable parallel–port device such as the IC 8255A is initialized for simple input or output and for handshake input or output by choosing kinds of modes. The hardware connections and the programs can be used to interface microprocessor trainer and a personal computer by using IC 8255A. The assembly programs edited on PC-s editor can be downloaded to the trainer.
