selling a HP 35 in good condition Message #1 Posted by Ingmar Tengler on 11 June 2003, 11:05 a.m. Hello everybody, i'm about to sell my dad's hp 35. i guess i wont have to tell you anything about that great invention hp made there quite a few years ago... it is in very good condition, only shows a little wear around the on-off switch. it works just like a new one would, and the led's are still quite bright. only the battery has been removed long time ago. so it has to be run with the ac adapter. i still have the original leather case and the original hard plasitc box as well it is the version where to top buttons are not printed on the buttons... if you are interested i will send you very detailed pictures... please contact: ingmarusa@gmx.de

However, please note that there is a "Classified" section of the HP Museum where you can post an advertisement. Simply click on the "MOHPC" at the top of the page to go to the Museum home page. May I also suggest that you don't run your calculator on the charger without batteries. You risk damaging the unit. Evidently it has not happened so far, but it could happen. Good Luck. Larry

Re: selling a HP 35 in good condition Message #3 Posted by David Ramsey on 11 June 2003, 12:05 p.m., in response to message #2 by Larry Corrado, USA (WI) Why shouldn't he run his calculator on the AC adapter without batteries? As I recall, even the manual says this is OK...

Re: selling a HP 35 in good condition Message #4 Posted by David Smith on 11 June 2003, 1:32 p.m., in response to message #3 by David Ramsey The HP35,45,70 and 80 were designed to be run without the battery installed. There is a small chance that a 65 or 67 card reader chip could be hurt this way. It is the best way to fry a Woodstock series machine. Not good for Spice series machines either.

My Mistake... Message #5 Posted by Larry Corrado, USA (WI) on 11 June 2003, 4:04 p.m., in response to message #4 by David Smith I've always taken it as a general principle that one shouldn't run a calulator on the charger without batteries. Of course, the reason is the voltage regulation that rechargeable batteries provide. Evidently, that's not a problem in some HPs. I stand corrected. Thank you, David and David. Larry
