IPC: G06F13/37
Filed: 1983-01-18
Abstract: PURPOSE:To eliminate the need for processing by identifying automatically whether or not an input/output controller is mounted to transmit a signal to the input/output controller. CONSTITUTION:When the input/output controller 3 is mounted, since an output control line 12 of a buffer 11 is grounded by the input/output controller 3, the buffer 11 goes to a high impedance and a signal on a priority input signal line 5 is transferred to the input/output controller 3. On the other hand, when the controller is not mounted and the slot 4 is idle, the output control line 12 is opened and pulled up by a pull-up resistor 13 and goes to H level then the signal is transferred to the next stage as it is. Thus out of the input/output controller 3 requesting input/output, one holding L level at a priority line 6 of the input side has the highest priority.
