RE: HP-34C external battery charging

Short of finding an HP-34c adapter or 82103a external battery charger, what other solutions are there to charge the batteries? If you have access to a bench power supply, you can fabricate a pretty simple set of contacts to insert. Another page on the same site shows the connector and lists the power settings (oddly, it's 9V AC). This is probably the easiest of all HP power cords to replicate due to the exposed contacts. http://www.keesvandersanden.nl/calculato...e_chargers Also: Note that the 82103A power pack requires the same AC adapter as the Spice series machines use. If you are planning to acquire one sooner or later, I can loan you one for the interim, contact me off-list to arrange. --Bob Prosperi |
