Vintage Hewlett Packard HP-25 Scientific Calculator VGC

Description

Vintage Hewlett Packard HP-25 Scientific Calculator Very Good Condition. No books or AC Adapter. Manual available online free at Slide rule museum. Battery pack was modified by a previous owner to accept 2 aa batteries. Lights up and calculates. I didn’t find a test for it like I have other hp calculators. If that’s important I would be happy to try.
“As is mentioned in the owner's handbook, with the HP-25 "you have at your fingertips a tool that was unavailable to Archimedes, Galileo, or Einstein. The only limits to its flexibility are the limits of your own mind." To be sure, there's an awful lot of calculating capability there, for such a small package!”
