To provide for a protected-signal interrogation of a duplicated matrix by a number of computers, each matrix (MA, MB) is associated with two decoding circuits (DAA, DBA; DAB, DBB) with priority circuits (PAA, PBA; PAB, PBB) for selecting the computers and connecting them through to the row lines and matrix. The computers (RA1 ... 4, RB1 ... 4) are divided into groups which have access to both matrixes via different priority circuits, the column lines of the matrixes being connected in parallel to all computers whilst the row lines are additionally connected back to at least one computer of each group. <IMAGE> |
