DEC produced several boards (the M9014, an [[DEC card form factor|extended height dual card]], and the M9042 short dual card) cards to replace the standard BC11A [[UNIBUS]] cable. They plug into the same 'UNIBUS In' and 'UNIBUS Out' backplane slots as the BC11A, and contain three 2x20 headers for 40-conductor flat cables (known as H854 cables in DEC parlance); a pair of these cards, and three cables, perform the same role as a BC11A cable.

Both of these cards use the header pinout given below, so they may be used interchangeably. Following standard electrical engineering practise, every alternate wire in the flat cable is a ground: the active pins are B, D, F, J, L, N, R, T, V, X, Z (using the Berg connector pin nomenclature).
