'Strue. The first time I had to reset my ver E I was quite confused. There's a hole under _both_ top feet, but pushing the one that worked before (on my [stolen] vers. A and D) had no effect. And it had a little 'R' by it, even on the ver. E. So I looked under the _other_ foot, and voila! Two holes... Now for the stupid HP trick: to quote from the manual, p. 660, "To maintain product reliability, avoid getting the calculator wet and observe the following temperature and humidity limits: " - Operating temperature: 0 to 45 C (32 to 113 F)." The trick here is that it doesn't have to be 113 deg F for the calculator to be operating at 113 deg F. Tricky, eh? I was fifteen minutes from a presentation of my latest hardware/software project: a maze-navigating robot controlled by an on-board computer - the 48. The only space big and flat enough to set up the maze was the courtyard in front of our library. Being good Harvey Mudd students, all of our previous tests had been conducted at or after 2 a.m. But we were making last-minute adjustments and calibrations and generally revelling in the fascination any sort of moving thing holds for passersby - at 1:15 on a sunny SoCal afternoon. Needless to say, memory was lost seconds after one of us picked up the calculator and said "gee, this is hot." So we scrambled for old versions on the computer and madly tried to remember all the fixes we had made in the last day. There were a lot. We never got it working as well as it was the few minutes before it ailed. So how is this calculator useful for surveyors? It wasn't out in the sun very long. Oh well. > I__) _ _I _ _ Tim Strong <TDSTRONG@MTUS5.cts.mtu.edu> ***************************************************************************** ** Bill Gribble Harvey Mudd College, Claremont, CA ** ** bgribble@jarthur.claremont.edu Never heard of it?
