The sophisticated HP-65

[TomC]

A couple interesting relevant points:

I had several programs accepted into the 'HP65 Users Library' back in the day.

Also, while in a numerical methods class (in the days of Fortran IV on an IBM1130 mainframe), we had a 'drag race' with my HP65 for estimating Pi via inscribed and circumscribed polygons.

While not a particularly sophisticated program, it uncovered the numerical accuracy superiority of the precision of the HP65 compared to Fortran of 1975 (I do not recall if I used single or double precision).

After this experiment, my Mathematics and Engineering profs ceased making fun of me carrying and using that expensive 'toy'!

So, what is the most sophisticated program you’ve written for the 65?
