replacement for 41CV Message #1 Posted by Cloyd on 24 Feb 2004, 5:57 p.m. My HP41CV just died the other day after 23 years of nearly daily use. What calculator does HP now make that comes close to the 41CV? I would want the RPN logic and the alpha-numeric data entry and programming abilities.

Re: replacement for 41CV Message #2 Posted by GS Leong on 24 Feb 2004, 7:45 p.m., in response to message #1 by Cloyd Cloyd I hate to tell you this but hp dosent make anything even remotely close to the 41 series. I suggest you try and find another 41. Sorry

Re: replacement for 41CV Message #4 Posted by Karl Schneider on 25 Feb 2004, 1:05 a.m., in response to message #3 by db(martinez,california) Cloyd -- I would second db's advice. Randy did a fine job on my 1984 (fullnut) 41CX. Yours is also a fullnut, because it's at least 23 years old. Fullnut 41's are much more repairable than the later (1985-) halfnut architecture, but also less reliable. I think that you should find a 41CX to replace your CV. Halfnuts will be newer and probably have fewer problems, but the display and keyboards are not as good. -- Karl S.

Re: replacement for 41CV Message #5 Posted by Ron Ross on 25 Feb 2004, 4:29 p.m., in response to message #1 by Cloyd Best is to buy another 41c series (depending upon your needs and desires). The newer Hp33s would work as a general RPN scientific and keeping it small, reasonable and easy to get. Drawbacks of course are the poorer keyboard, modules you may have, and limited variables. An older Hp48G might work well for you (or it might not as it is a graphics and considerably larger in size). It has everything a 41c series has except Hp-IB interface. It has a serial port and lots of programs available. Programming is in RPL (both better AND worse than your 41, many arguements both for and against, and all are valid). Still has the quality Hp feel and proper placed enter key. Also, fairly cheap to get though used via ebay. An Hp11c might also serve you well, and these typically sell for a little over $100 via ebay. Bargain compared to other Hp's (for a low end scientific), but a true power Hp41c user would feel cramped. A nice upgrade (if you don't need Hp-IB, timer, or some specialized module) would be an Hp42s. This has all the math features plus many, many more of the 41 series, is faster, easier on batteries, uses easier to find batteries and will take any program (aside from timer progs of the 41cx) of the 41c series. All have to be keyed in as that is the only input available. The Hp42s is my favorite machine and I would like it better if it had the I/O of the 48G series. That said, I always have a 48G on my desk for a couple of reasons. It is expendable, it has tons of features, the most used by me, is its units conversions and solver. If you do not use your scientific functions you could buy an Hp17Bii and get a real good RPN calculator with lots of potential (outside of trig functions). Has good statistics and a real easy to use solver. These are typically $50 or somewhat higher. Same general calculator as a 42s except a business calculator (but there is a good reason why a 42s gets $200 + vs $50 of the 17Bii). Actually the solver on my 42s seems faster to me, but isn't quite as easy to set up. But once I enter the equation, I find the 42s to be much better to use. Depends upon your real needs: If you need another 41, you will have to buy a 41. If you just need a vertical RPN pocket scientific, I suggest looking at a new 33s. Hope all this helps.

Re: replacement for 41CV Message #6 Posted by Andrés C. Rodríguez (Argentina) on 25 Feb 2004, 5:44 p.m., in response to message #5 by Ron Ross Just to suggest another way, you can run a HP 41 emulator on a Palm or Pocket PC device. You will miss, at least, the physical keys and the battery duration, but it may be a valid option depending on your interests, needs or activities.

Re: replacement for 41CV Message #7 Posted by Diego Diaz on 26 Feb 2004, 7:33 a.m., in response to message #6 by Andrés C. Rodríguez (Argentina) Hi Cloyd, I'll just sum to the previous advices myself and, apart from that, just a recommendation on behalf of the "hardware guys": If you decided not to fix your unit (I personally think you should try fixing it), please, please, please... do not throw your 41's "body" away. Every piece is valuable to fix other units, sure you can sell or give it to a good "fixing home" near you and help saving other's 41 live. ;-) Best of lucks. Diego. 123456

Re: replacement for 41CV Message #8 Posted by cloyd on 27 Feb 2004, 10:18 a.m., in response to message #1 by Cloyd I have already loaded the 41 emmulators on my PC and my IPAQ. I do appreciate everyone's suggestions. I will probably send it off to see if can be repaired. If not I will donate the body (as suggested) to the repairs of others. (I had actually considered giving it a proper burial until I stumbled on this forum.) Luckily I do have a 41CX to fall back on. Does HP not read this forum and how valuble these type of calculators are? Are they blind?

Re: replacement for 41CV Message #9 Posted by Wayne Stephens on 5 Mar 2004, 7:12 a.m., in response to message #8 by cloyd Answer to your two questions (in order): Probably not. Yes. Take care. Wayne.

Re: replacement for 41CV Message #10 Posted by Jim Chumbley on 28 Feb 2004, 3:13 p.m., in response to message #1 by Cloyd Hello Cloyd, I'm sorry that your 41CV died. I just bought an HP-41CV today that is in excellent condition, very clean, no corrosion at all, all keys work perfectly and have a completely uniform feel across the keyboard. I bought it for a very low price and would be glad to sell it to you to replace your broken one for $100. Is that appealing? Jim Chumbley ------Very sorry if this message is posted to the wrong index. Edited: 28 Feb 2004, 3:18 p.m.

" Kermit " Couëtte on 1 Mar 2004, 11:29 a.m., in response to message #10 by Jim Chumbley Mar 01 , 2004 Hi Cloyd , In addition to the very kind offer made by Jim , may I share a similar experience which happened to me recently and which I was able to solve in a manner I am extremely happy with . ********* May I suggest that you take a look at some of the HP41 Emulators available to-day . I know of 2 Emulators running on PC : Emu41 by Jean-François Garnier and V41 by Warren Furlow . Their speeds are amazingly fast and fascinating compared to the original HP41 . And let the authors of other Emulators I do not know of , kindly forgive me not mentionning them :-). ******** On the other hand , if what you need is to have a " HP41 running in a handheld " , then let me highly recommended you taking a very close look at the various Emulators for HP48/HP49 by Hrastprogrammer ( <http://hrastprogrammer.tripod.com> ) . Some of them are free shareware , and others - much more powerful - are not free software . True , there is a small early difficulty in having an HP48/49 emulate the good old 41 since it is not possible to get an exact keys matching . However in this specific respect what Hrast did is extremely logical . The only difficulty which arises at the beginning occurs only during programs/operations " keying " , but it does not occur when running existing software . And after limited use , you feel very comfortable on HP48/49 running all your HP41 software . In other words , I am absolutely ENTHUSIASTIC using Hrast's Amazing and Extraordinary Emulator . I really liked - and still like - my HP41 CX's , and still have 2 of them in good running condition : only Hrast could have me daily use my HP48/49's instead , and not regret my old machines !!! Because everything my old CX's did , his Emulator does it , and much better and faster , and all this in a handheld !!! If you wish to read additional - including third party - information/rating about Hrast's achievements , do not hesitate to look at this Forum Archives " Forum Archive 14: Dec 2003 - " under the title " " ASTRONAV software, HP-41X and other things ..., HrastProgrammer 15 responses " **************** Hopefully with all the advice you got , you can find a good solutions which fully fits all your needs ... and keep me posted . Best Regards from " Kermit "
