Has anyone found a source for the carrying case (part #92169A) for an HP12C Financial calculator?

I sent for repair my financial calculator model HP12C Order No. CSS-3258 on July 10 2007 in Caracas, Venezuela. Received it back a month later without any repair performed.
I called the service center in Caracas and was told that the calculator did not have repair due to lack of spare parts and should be disposed.
I have been using HP´s since my college and postgradute studies. Can not believe a HP does not have spare parts!!!.

Go to Hpcalc.org and search for memory expansion. That will also offer a guide as to how to open an Hp48. If it is a keyboard problem, you might contact some repair places such as fixthatcalc.com before you ruin your calculator.

I am also looking for a battery cover that was lost for an HP-12 financial calculator. The batteries come out during use and tape doesn´t really work all that well. If this is possible without buying a new financial calculator can someone please let me know. Thanks.

I saw your post when browsing for batteries for my vintage HP41C. It is a flag setting, but I don´t remember which one because I can´t turn the thing on (Use the: shift "SF"). It is for European users where they switch the decimal with the 1000s place commas.

In reply to Marla :
Hello, I also have a "comma" problem, but on my 41C. The advice for Helene (holding the decimal down while off, then turning on) didn´t work. Is there something special for a 41C? Marla

I have a HP10C calaulator since 1982 and recently found that the decimal point has become a comma on showing the digits e.g. 10,0000 for ten and 10.000 for ten thousand. Could anyone tell me how to eradicate this situation. Please e-mail at solidus@netvigator.com.

Thanks in advance.

Thanks for reply Keith - you seem as though you are a sailplane pilot. Playing with my computer at 0500 ´cos my missus has run off and left me.

Where can I get my HP-41C repaired ?

What were you doing Playing with your computer at 5am? I trust you have the battery`s fitted as intended. I noticed my gps was slow to start the other day, it seems as if micro processors go into a kind of hibination when not used for some time!

To Whom It May Concern Regarding HP33s I bought recently, the enter key should not be placed side by side with the arithmetic signs. It´s confusing when i am using RPN system. Furthermore i got an HP 41c and it´s not operational. Please tell if you can still repair it. Thank you.

I attempted to send an email concerning a problem I am having with my HP calculator and the message would not go through. I used the chia@mac-net.com
address. Is there anywhere I can contact for help with my problem? I had a similar type question about a year ago, but I have lost the phone no. (in the US) which I used. That call resolved all the trouble very quickly! Hope that I can get help this time.

I am the County Surveyor in Mesa County, Colorado.
Recently an HP 41CX was turned into my Office in Grand Junction, Colorado. The Serial Number on the calculator is 2822921396. It has a survey pac and three memory modules. Is there any way of contacting the last known owner of this calculator? I can be reached at: lstiles@co.mesa.co.us. Thank you for any assistance you can provide.

Does anyone know how the key touch/feel for the HP 33s compares to the HP 32sll. I loved the exactness of the 32 but did not like the 49g´s feel. Does anyone know which model the 33 comes closest to?
