Welcome to my listing for a Hewlett Packard HP model 25 scientific calculator from the late 1970s. This RPN programmable calculator is in great condition -- has a battery door and a clean battery compartment, has a bit of overall scuffing from ordinary use but no cracks or chips. Best of all, it works: the red LEDs light up, and the keys have a nice responsive clicky feel. The original "battery pack" of rechargeable batteries has been opened up, and those batteries were removed and rep...laced with ordinary alkaline batteries. In Photo 4 you can see two strips of tape holding the plastic battery pack pieces around the new batteries. There's a former owner's name/address sticker on the back side, which I've left on for historical interest. There is no case, no charger pack, no brochures or manuals -- just a great vintage calculator you can really use.
