HP-11C Self-Test Help
I am new to this forum and hope someone can help. I have an HP-11C calculator that I came across in my late father's belongings and am trying to see if it still works. I found instructions for running self-tests and the one using the "X" key worked fine. But when i try to do the keyboard test, I don't get an error code, but I do come up with a different number value on the screen at the end of each time I try the test. I have pushed each key in sequence left to right, top row to bottom row. I wasn't sure if i was supposed to include the "on" button in the sequence, but when I included it, the calculator just turned off. And if I push every other button in the testing sequence except the "on" button, I just get different values at the end each time. I don't know what I'm doing wrong or whether the calculator is just malfunctioning. Any insight would be appreciated.
