Sorry about posting the two previous messages to this list. I realized after I had sent them that this is not the list for that. But, I took my calc apart and saw that one of the wires to the cap had come off. I soldered it on and it works fine now. And by the way, with the wire off, some programs ran faster and some of them even ran slower. Ed Plese, Jr. (eplese@lnd.com)
