- Press the EXECUTE button to begin the test. - The test result (OK or NG) is displayed within twenty seconds. If the test result is NG, not only the respective IC, but a break or short circuit in the ADDRESS/DATA BUS as well as in any of the strobe signal lines may be the causeof the failure.
Page 21
- The test is carried out repeatedly. Data is saved and loaded, and then the two data sets are compared. The number of times that the test results in OK or NG are counted and displayed on the LCD. To interrupt the test, press the STOP button.(refer to Fig.25 - Even when the Floppy Disk Drive is functioning properly, the test...
