Chapter 5 E40S/E60S Fault Finding
FileStore Service Manual 101
The correct voltages are as follows:
 2 MHz expansion bus D0 to D7 and A0 to A7 should all be 2.5V.
If for example, D0 to D7 are all at 0V or a mixture of 0V and 2.5V, then one of the buffers is
probably enabled.
5.5 Final checks
If the procedure outlined above fail to uncover the fault, then as a final check, you should
refer to Appendix A - Test Equipment, which contains more thorough tests of the FileStore.
The tests to run and the order in which to run them are as follows:
 Run all the tests in FServTest
 Run FServFmt on each disc
 Run FServInit on each disc
 Run FServSoak, running all the test patterns on each disc.
