The solver on those machines works as a programmer would assume it would. There are at least two equations in the Applications Manual that work fine on the 17b/17bii, but won't work on the 17bii+ without some modifications. Cyrille has said in the past that the solvers are not exactly the same; Kinpo added an extra evaluation pass that causes unexpected and unwanted behavior, such as you experienced with your equation.

The 17b and bii are marvelous machines, and I continue to use them daily.

Well, I have the HP-27S, one of my all-time fav HP calculators, but I keep running out of memory on it and the legibility of the display have started to nag me, so I was planning to sell it.

I was hoping the 17BII+ could be a replacement, but I might have to reconsider. It has the memory going for it and a very crisp and clear display.

I will do some more investigations of the Solver and make a decision.
