I was bored and found a HP-27S

OK, good point!
The HP-27S lacks conventional programmability and that is a shortcoming for me as well.
But for the price I have paid for it - just 28 Euros + s&h, and considering that it is in good working condition (well, at least it was advertized as such) and despite showing some scratches in the display frame, I still believe it was a nice acquisition

When I receive it at home and when I'm back to Lisbon, I will report again.

Sounds like a good deal. Katie reminded me about the 27s solver programming, I had forgotten about that. In my opinion, one of HP's greatest achievements was the inclusion of programming constructs such as IF, sigma (loop), and L() and G() in the solver found in several calculator models, including the 27s. This made the solver more than just an equation solver; it is a real minimum programming language.

HP should have received some type of award for this solver, but we are all beneficiaries.
