ABSTRACT:
A peripheral dependent circuit board is used for providing the specific functions required for data transfers between a peripheral terminal unit and a data link processor. The data link processor is a peripheral controller made up of a common control circuit card which provides standardized functions for all types of data link processors and said peripheral dependent board which provides a specifically required function for a particular type of peripheral terminal unit. The peripheral dependent circuit board provides logic means for executing micro-code word operators received from said common control circuit card and provides multiplexor means for selecting a source of data that is to be transmitted for temporary storage in a RAM buffer memory on said common control circuit card. The peripheral dependent board provides address logic means for formulating addresses to be used for the reading and writing of data out of and into the RAM buffer memory and has a jumper to set a unique address signal which identifies the particular peripheral controller.
