Error in wikipedia article on HP-35s (Solver)
Message #1 Posted by x34 on 23 Sept 2011, 1:13 a.m.

wikipedia article http://en.wikipedia.org/wiki/HP_35s says "Equation solver (a feature first seen on the HP-34C)". While it is true that HP-34C was the first with RPN Solve, what was the first calculator with algebraic ALG EQN Solver?

Karl Schneider's article http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/articles.cgi?read=556 does not give the exact answer, what model was the first with EQN Solver? HP-17B?

Fixed!

That's the beauty of Wikipedia: we can fix errors like this if we find them and, especially, if we can include references backing up our changes.

I generally won't waste my time with that abortion of a project

You're referring to the 35s and not Wikipedia, right?

No, wiki. If you write something, it just gets scribbled off and replaced by garbage. And it takes time. I'd rather generally get paid for using my real expertise :-)
