This circuit divides the pulses, detected from the electromechanical table of the machine, and directs them to one of four or more counters. Each counter represents the points score of one of four players. The system has four five-figure digital display counters which are controlled by a memory. This memory is capable of adding or multiplying the pulses after channel ection. It can also inhibit or annul according to the programme set on the pin ball play table. A fifth display counter sums and displays the free plays after a predetermined points score of the play programme has been exceeded.</p> |
