The 27S is an excellent machine! If it had RPN, it would be my daily carry machine, but alas... it doesn't.

The Pioneer Solver it has is a truly powerful and flexible tool, learn it and get to know its quirks early on and you will be a much happier user. Of course basic use of the solver is described in the owner's manual, but I suggest that once you know the basics, get the manual "Step-by-Step Solutions: Technical Applications (27S/19B)", which really does a far better job of demonstrating it's power, use and flexibility.

Enjoy your 27S!

I agree with every word, Bob.
That's why merging the 42S and the 27S in Plus42 was such a great idea
