System for providing self-selection arbitration among a plurality of slave processors connected to a VME back plane. The slave processors are connected to a common ID bus, interrupt line, and acknowledge bus. Slave processors contend for access to the VME back plane by asserting an interrupt level unique to a group of slave processors on the interrupt line. Simultaneously, the contending slave processors apply their respective addresses to the ID bus. When a contending slave processor receives an acknowledge over the acknowledge bus from a master processor, and senses its own address on the ID bus, it has successfully won the right to transmit data over the data bus.
