Recognizing HP 41 model (C, CV or CX) - Francis - 09-23-2005 I have the opportunity to buy a 41 but the buyer as a doubt about the version. The front plate clearly shows 41CX but he’s not able to find any time functionalities. So, what could be a ‘simple test’ to check the version? Please keep in mind that I have to explain this to him without having a 41 myself !!! The serial number of the calculator is 2350S40219.
Regards, Re: Recognizing HP 41 model (C, CV or CX) - Vieira, Luiz C. (Brazil) - 09-23-2005 Hi; one of the simplest tests to recognize the existence of the timer module is by pressing [SHIFT][ON] after having the calculator turnned on ([SHIFT] is the golden key, that activates the SHIFT indicator in the display). If it simply turns itself off after the [SHIFT][ON], then it is surely not an HP41CX or it has a bad time module. Also, try [SHIFT][CAT][2]. You should see: [TIME FCN 2_ ] (the underscore represents the version indicator)Any other HP41 (C or CV) will do nothing after CAT 2, unless it has a ROM module plugged in or, if hacked, an internally connected extra ROM. Hope this helps. Luiz (Brazil)

Best regards Re: Recognizing HP 41 model (C, CV or CX) - Richard Garner - 09-23-2005 Hi Francis, One way to find out if the 41 is a CX version is to do a catalog 2. Shit Key (Gold Key) Enter Key 2 This will run the system catalog for plugged in modules/devices. The CX funtions will show up as -CX Time
-CX EXT Fcn
Oops! (was: Recognizing HP 41 model (C, CV or CX)) - Vieira, Luiz C. (Brazil) - 09-23-2005 Hi, Peter; you are right. I don´t have my CX in hands right now, and the [TIME 2_ ] plus [CX TIME ] are the correct output messages. Thanks.

Re: Recognizing HP 41 model (C, CV or CX) - don wallace - 09-23-2005 Hi Francis. You can try to view the CLOCK: [ON] [SHIFT] [ON] Or try to display the current time: [XEQ][ALPHA]t i m e [ALPHA]

Re: Recognizing HP 41 model (C, CV or CX) - Randy - 09-23-2005 You could have him clear the unit back to factory defaults with a simple proceedure.
Re: Recognizing HP 41 model (C, CV or CX) - Garth Wilson - 09-23-2005 There must be many ways to tell a cx from a cv with modules in it, but one extra-quick one should be to try the catalogs above catalog 3. The cx adds catalog 4 for files in extended memory, catalog 5 for alarms, and catalog 6 for key assignments. I think that if you try these on a c or cv, you'll just get catalog 3 (like you do if you try "catalog 7" on a cx).
