HP-97 I register problem



#6

My HP-97 is not storing data in I register. If somebody can tell me,which IC or part of the calculator is sick?, or if can be fixed?.


#7

It would be surprising if one register only failed. If you have the standard applications pac 1 there is a 'test&diagnostic' function which you could use. Perhaps more likely the key is not working due to dirt or some mechanical problem?


#8

Thank you for response. I found this problem by running test program from applications pack1. ERROR CODE 0


#9

Let me look at the documentation and I'll come back to you on this, meantime, your sure that the rest of the memories work fine? Its just I cant believe that a whole memory would fail, maybe bits of it so that the number stored is not the number recalled, but the whole thing?


#10

Yes , other registers work fine.
