HP-25 / HP 41C Message #1 Posted by marsh on 27 Mar 2007, 1:21 p.m. hello, today i found two old HP calculators from my father. i wonder if they still have some value. HP-25 serial: 1605S32286 equipment: original HP leather case, ac adapter, user guide (german) HP41C serial: 2041A01654 equipment: only the leathercase and 2 memoryunits condition: both are used(of course) and a bit dirty, but they still work.

If they work and clean up well, I would say each of them would easily bring $200 (US dollars) or more. Some of the software modules for the HP 41C bring a handsome price when sold separately...what modules do you have? Beware though...if you start working with them, you won't want to part with them :) Best regards, Hal

Re: HP-25 / HP 41C Message #3 Posted by marsh on 27 Mar 2007, 2:14 p.m., in response to message #2 by Hal Bitton thanks for the information i have no idea what software modules that could be. i don't even know how to find out if the memory modules contain anything. these are only the standard memory moudles that were shipped with the hp 41c (i guess) and i have to update the condition of the HP-25. the battery cover broke on first touch (had a weak point i guess) and after running for 5 minutes on the ac adapter the display is only flashing now.

Re: HP-25 / HP 41C Message #5 Posted by Ron Ross on 27 Mar 2007, 2:40 p.m., in response to message #4 by marsh You may want to look further down on the threads about plugging in the Hp25 w/o a battery pack. It is very likely you may now have a paper weight instead of a collectable calculator (I hope not, but you will need to get a battery pack to confirm).

Re: HP-25 / HP 41C Message #6 Posted by Dia C. Tran on 27 Mar 2007, 1:53 p.m., in response to message #1 by marsh They certainly have values. Check the "Prices and Rarity" section on this website as well as check completed ebay listing. If the calculators are in very good condition then they are worth about the prices when they were new. Of course sometimes they go on ebay for higher prices but sometimes you can get them for almost nothing at a garage or estate sale.
