HP-97 I register problem


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?.


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?


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


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?


Yes , other registers work fine.
