13.3 INTERCONNECT BOARD
For mechanical support and electrical interconnection, each BCD board is
shipped with a small 5-pin INTERCONNECT board. Insert onto the main
board pins immediately behind the right-hand side of the display board. The
BCD board itself (component side down) is then plugged into the
interconnect board at J20, with the PCB connection fingers protruding from
the case rear. For assembly detail, refer to Figure 5-4 (in Section 5).
