Most current HP 33s models Message #1 Posted by Joe Edwards on 14 Jan 2006, 9:08 a.m. Hey folks, I ran across a post somewhere that stated there have been several iterations of the HP 33s calculator. What is the condition of the most current version (bug wise, LCD wise, tiny decimal point wise, etc) and how do I tell which version is which? Thanks for the help in advance. Joe Edward

Difficult but not impossible. You need to run the H.MS DMS routine (check to see if it mishandles negative values) and the Polar-Rectangle routine (test to see if it gets confused going from 90degrees r=1 to X,y and tehn back---if it gives 270 degrees it hjas the bug.
