Re: HP 15C Message #2 Posted by Patrick on 11 Aug 2004, 1:49 p.m., in response to message #1 by Nam Dang
As many people here know, I am a huge fan of the HP-15C and own several copies. I recently purchased the program MathU Pro for my Palm Tungsten T3 from Creative Creek, http://www.creativecreek.com, which is an HP look-alike and work-alike.
First thing I did was to write an HP-34C / HP-15C -like Solve program for it. After I got it mostly debugged, I ran it through all the examples in Kahan's article on Solve. It was able to get the same results as the HP-15C at each iteration. The icing on the cake was that it found the solution 400 times faster!
Naturally, a refreshed HP-15C would be faster too, but then one of its beloved traits, the fact that its batteries lasted on the order of decades, would surely suffer. Small price to pay I guess.
