RE: HP-21 repair
I managed to get a cheap HP-25 awhile back which was advertised as not working. When it arrived, I connected some batteries and it was dead. I opened it up and found moisture on the circuit board. After cleaning it up and drying it out, it sprang into life.
It does prove that simple things like that can make the calculator seem faulty, so a good inspection might help get it going. Other than that, as Bob pointed out, maybe the Arduous Calculator Thingy has failed. cheers Tony |
