Sure, I know :-) But attaching a GPS module, whose on-board processor alone has about 100.000 times the memory capacity and processing speed of an HP-41, is quite a violation of historic accuracy, isn't it?

What I would find more challenging is to implement the equations required to determine the geographic position (lat/long/altitude/time) from the pseudorange measurements of the GPS receiver on an HP-41. This would also require the almanac and ephemerides of the satellite constellation of course... If someone finds a way to fit that into an HP-41, I am going to be deeply, deeply impressed!
