This listing is for a Giddings and Lewis Electronics Digital I/O PCB Board assembly, part number 501-03855-00, with secondary reference number 502-03064-10 visible on an affixed label. The board is date coded 7/83 RB. The assembly consists of two mirrored Digital I/O sections, each with labeled INPUT and OUTPUT edge connectors, screw terminal input positions numbered 1 through 26 visible in photos, individual fuse positions labeled FU1-0 through FU1-15 per section, and individual LED indicator positions labeled LED1-0 through LED1-15 per section.
