Re: HP 21S Manuals Message #11 Posted by Ron Ross on 19 Jan 2004, 2:40 p.m., in response to message #1 by Walter B
Of course an off the shelf Hp21s came with the manual. However, not many people purchased the Hp21s as it was about twice the cost of an Hp20s and for the money, you could buy an Hp22s which WAS better. The Hp22s had a solver, the Hp20s and Hp21s did not. They are programmable, but no solver. Therefore, finding an Hp21s manual will be difficult. However, it does program exactly like the Hp20s but with three different built in libraries and the stats features (which I believe are pretty straight foward, and located under the numerics).
I do hope you can find a manual, I bought my 21s as a surplus service replacement and did not recieve a manual either. My wife contemplated using it in a stats class (and we both explored its many features), but she was much better served by her 27s (no graphics calc's were allowed).
