HP 41C solver problem

[Massimo Gnerucci]

Having brought out of the drawer my almost 40 y.o. HP-41C box I was amazed, once more, by the quality of the materials (the box, manuals, module holder, calculator, case, even the Eveready N cells box!, are still in like pristine condition).
And I was reminded of fond memories, while devouring that complete and easily readable manual, coast to coast.

Thank you Hewlett·Packard from the Seventies.
