Old hp calculators Tags: Hewlett Packard Last response: September 26, 2011 3:56 AM in Other Consumer Electronics Share fgernhardt September 23, 2011 4:57:13 PM Hello, I was given an HP28S Advanced Scientific calculator. It does not have the manual and I would like to use all its capability. Does anyone have, or know where to find, a user guide for this calculator?
