This trainer has IC 8212 as input / output IC. In this experiment 8212 is used as OUTPUT module. This has one seven segment display as output indicator. Each output bit of this 8212 is connected to each segment of the seven-segment display. The eighth bit is connected to decimal point. Therefore a program can be written to excite all the segments or a few to display any character within seven segments. You need an external 5V DC @ 250mA power supply or electronic design experimenter model EDE-1.
