Abstract
PURPOSE: To eliminate the need for a testing cable or checker, etc., and also to simplify the connection of a control signal by making the immediate test of an input-output control part by changing a computer unit over to an input-output device.
CONSTITUTION: When computer unit CPU1 and input-output device 3 are connected together via terminals 4 and 4' of a connector, the relation between terminal 4 at the CPU1 side and device 3 is so fixed that respecitve lines 5,5'...10, 10' are constituted into a mutual series circuit. Further, when CPU1 is disconnected from device 3, output line 5 and input line 8, command line 6 and input strobe line 9, and output mode line 7 and status line 10 are respectively connected by folded circuits. To connect CPU1 to a checker, the same connections as mentioned above are made in the internal checker part to eliminate the need for cables for testing, the connections of control signals.
