Same deal as a few other S-box handle boards. It's a standard dual wide M9405 board riveted to the S-box handle frame and a dual wide blank spacer for the CD half of the slot. The two 50-pin D-shell connectors on the metal frame are connected to the two standard connectors on the base M9405 board by two short ribbon cable jumpers.
