I kept a tiny notebook in the case with my HP-25 as my "non-volatile" program storage. And I remember the manual's suggestion to press "1" in RUN mode to minimize current draw if the calculator was kept on to just to preserve memory. As for factorial, that's an interesting question. TI obviously thought it was an important function for general use (it was on the TI-50), but HP clearly didn't share their enthusiasm. I think the first HP with factorial was the HP-65? |
