anyone else. i know hp actually put out one ofthe versions of the hp on the iphone. amazing to me the cult following on this calc.
I guess it first being made in 1981, and still in production, means the HP-12C spans a few generations.
Devices like Android phones are perfect platforms to emulate classic calculators. You can have the real one, one on your desktop, and one on your phone.
Hard to believe - the 12c introduced in 1980/1981 - one of the premier technologies at the time (keep in mind, no one had cell phones then)... and for it to STILL be a current product ~29 years later - amazing - what other electronic product has had anywhere near this life?
I'd love to see a 12C Droid app. Tried downloading the RPNCalc free app, but it doesn't have a fin calc, and the website provided just errors out.

I can't think of anything else comparable thats for sure.
RPNCalcPro (paid) version has the financial calc - its actually pretty good.
I think one of the reasons why we haven't seen an Android version yet is the current lack of any opensource versions of the voyager calcs. Nonpareil HP calc simulator (Nonpareil: High-Fidelity Calculator Simulator) used to have them included, but licensing issues meant they needed to be seperated out.
I started using the 11C in Jr High - given to me by a friend that was a NASA engineer. I loved it when kids in class would ask to borrow my calculator and had no idea what was going on. 99.9% of the time, the first words out of their mouth was "Where's the equals?". lol.
I could go for an 11C on Android.

What about the HP 48? It is using reverse polish notation, too. The android app is named 'droid48' an can be downloaded free in the market.
Yeah thats a really cool port as well.
I think people like what they are used too. In the HP-12C's case, its a financial calc with RPN. The HP-48 is a complex scientific graphical calc. One of the main reasons why the voyager range of calcs were so popular was the fact they just gave you an answer without the frilly bits. And they looked kinda cool
Definitely would buy the HP12c app and hardly know anyone in finance who does not carry the 12C around. Great on the iphone not having to carry the 12C. I still have the same 12C I had in MBA school in 1979 to 1981. Amazingly great. Cannot use normal calculators anymore. It was great having exactly the same layout on the iPhone 12C. Am on withdrawal now without it in the Droid.
Hi all; I'm the author of RpnCalcPro. It doesn't have the same layout as the HP12C (I intended to use it in portrait mode), but it has all the same functions except for programmability. It's $5 at present. More info at RpnCalc Pro
I've gotten some feedback from people asking that I make they layout exactly like an HP12 in landscape mode, so I'm working on it. It's a little tricky because an android screen is much smaller than a real HP12, so squeezing it all in is rather difficult. I have it working now for the Archos, and with a little tweaking, I can get it to fit on G1 and Droid. Look for the new layout soon.
Since I have a number of interested people here, I'd like to do a quick user survey:
Do you use the programming functionality of the HP12? I haven't seen a need to add it to the calculator app, but I might if there's a demand.
Do you find the HP12's n,i,PV,PMT,FV functions ambiguous? That is, do you have trouble knowing if the key will enter a value, or compute it? (I added a "Find" key to my calculator to remove the ambiguity, but maybe it's not needed.)
Also: the cash-flow calculations (Cf0, Cfi, etc.) Do you ever use these? Do you edit the stored values? Do you change the Ni values?
Other differences between the android app and the real thing: I have 20 memories, whereas I think the real one only has 10. The stack has 16 levels instead of 4. Statistics have their own registers rather than being stored in the main memory registers. I'm going to guess this doesn't cause anybody problems.
In general, I'm interested in whatever feedback you might have.
I wonder, given the current lack of opensource options for a developer to create a voyager calc, if we email developers of voyager emulators for other devices & attach this forum threads http address? Just to show there is a level of interest & people are willing to actually pay for an android version.

This sounds awesome Ed!
I've got RpnCalc Pro & think its the closest thing possible to the voyager calcs!
If you could mimic the programming capabilities of (say) an HP12c then I reckon that would be cool! And make it look like a HP12c then even better!!
The Find button is an interesting one. Personally I don't think you need it. It feels like just pressing "PV" for present value (like on a 12c) is 1 less button click than "Find"->"PV" on RpnCalc Pro.
biggest issue to me is how the add/subtract works (different than normal calculators). once you get used to it it is impossible to use a normal calculator.

Yes; the Find button is going away in the next version.
Very interested in this app. I don't run programs on the 12C, so that's not a big deal for me. I don't find the keys ambiguous; I've been using them for many years. I definitely use CF0 and the other subscript and superscript keys.
Ideally the app would look just like the 12C and still be easy to precisely hit each of the keys - I know that's a tall order. I used a 12c emulator on a Palm Treo that worked by showing only half the 12C at a time, requiring you to toggle back and forth. That really undercut the usability of it for me.
Good luck!
I need to put in a vote for the CF0 CFi functions. I use them alot on my 12C. I have used the 12C from Lygea on my WinMo phone for years. Lygea is able to fit the full functionality of the 12C on a smartphone screen in both portrait and landscape. You may be able to gain inspiration from their layout.
Lygea is developing Android versions of their calculators
FYI... I received the following email response to my inquiry as to whether Lygea would be developing Android versions of their HP12C an other calculators.
Hello,
Thank you for your inquiry and for your input.
Yes we do have plans to port all our products to the Android platform. We will let you know if we have any updates on this.
Once again, thank you for your interest and input.

Great. Cool thing is, with an emulator like this, if the iphone is anything to go by, people will own multiple versions of the same calc - simply because they can. Plenty of room for everyone.

Dear Ed,
RpnCalcPro is just what I was looking for but unfortunately international users cannot buy stuff off the AndroidMarket. Only freely available software is shown to us. A work-around this that I've seen (for instance for SplashData's SplashId password manager) is to buy it directly from the authors and then download the .apk from them.
Do you have any plans to providing RpnCalcPro this way?
Almost all real estate appraisers use the HP 12c. It's a requirement for a lot of the Appraisal Institute courses, and they teach a course on how to use the HP 12c. I've seen it on the iphone, and it's a wonderful tool. I prefer Verizon service and have the Droid...but I need the 12c. You think it's difficult to teach a 35 yr old a new calculator, try a 60 yr old.

Looks like Ed Falk has released his HP-12C mode for RPNCalcPro. Just downloaded the update on the market. It looks fab! Same key layout as a 12C when RPNCalcPro is in landscape mode!!! He's managed to squeeze most things onto the screen somehow.
It doesn't looks exactly the same aesthetically (ie exactly the same look as a 12c), but still looks like a HP calc thanks to the natural look of RPNCalcPro. Key layout is the same which is important!
Am very happy! :-) Thanks so much Ed.

Love the HP-12c key layout in landscape financial mode in RPNCalc Pro Ed! Been working thru some of the examples in the HP-12C manual - so far everything gets the same result! Excellent work.
Here is a screenshot of Ed's new HP-12c layout in landscape financial mode for RPNCalc Pro

Just bought the Pro version for the HP12c calculator. Well done. The keys are a little small, as you indicated, but certainly are very usable. For someone addicted to the HP12c method, this is a welcomed app.
Ed, I don't "program" my HP 12c. I do use the pv, fv, i etc. keys all the time calculating payments, values etc. I would suggest you contact some of the organizations that encourage their members to use the 12c and get thier input.

Thank you,
I second that.
For me too only free apps are available from Android Market.
I want to buy your app but I cannot.
As another workaround, for instance, I have bought the full license for Docs to Go and unlocked the full functionality on the app itself. Thanks!
This link will take you to HP calculator apps for the iPhone. Having recently seen a friend's 3Gs using the 12c, it's as close to perfect as you can get outside the calculator itself.
On Tuesday, the Nexus One vs. the iPhone 3Gs competition will begin in earnest. I'd love to see a fully-functional 12c - including keystroke programming - for Android. The other 5 or 6 apps in my decision criteria can be reasonable facsimiles, but the 12C app needs to be spot on!
Just $0.02 from a newbie here.

Thumbs up for the RPC Calc Pro. Not as good as the iphone app I played with on a friend's phone, but well worth the $5 and the best option right now on Android.

Thanks for this. I'm eager to see RPC Calc Pro on a Nexus One. That and 5 or 6 other applications are going to guide my choice between the iPhone & the Android path.
It's been great to get acquainted with just how thoroughly this forum covers the Android products. Still learning how the Android/Google contacts, to do lists, appointments, notes, etc., compare with the HP200LX. That was a product ahead of its time in many ways. I'm ready for Android to better it in every way.

That rlmtools version of the 12c does look awesome doesn't it!
Quite interesting they even have a 12c Lite that doesn't have programming either.
Ed has done a really good job with RPNCalc Pro. For $US5 its very good value. Am really happy with it.
Am sure someone else will also make a completely accurate version like the ones we see for the iphone eventually
Hi all; just a quick update. The latest version looks as close to an HP12 as I could make it. It's not programmable, so many of the functions don't do anything, but I've left the labels on for now.
This weekend, I'll be putting up a version with an improved appearance, especially on Droid.
I've been surveying my users, and NOBODY has said they program their hp12, so it looks like I won't be adding programmability to RpnCalcPro any time soon.

Lygea is able to fit the full functionality of the 12C on a smartphone screen in both portrait and landscape. You may be able to gain inspiration from their layout.
OK, the good news is that I do have the Cfo/Cfi functions. The only thing missing is the ability to edit the Ni values but I'll look into adding that functionality.
I never heard of Lygea before; I'll take a look and see if their screenshots give me any inspiration. I've been using RpnCalcPro a lot, and haven't had much trouble hitting the buttons, so I'll probably leave things as they are. I experimented with scrolling layouts to have bigger buttons, and found them nearly unusable. You really do need to have all the buttons on the screen together.
Great. Any news on the possibility of selling it via PayPal? I'm eager to buy this app but as an international user it's not available to me on the Android market.

Google's lack of support for foreign countries is the biggest complaint I've had so far. Why Google does it this way is not clear to me. (Sometimes it seems that the entire design philosophy of the android market is to make the experience as painful as possible for both sellers and buyers.)
Making an app available outside the android market would break the copy protection, but rumor says that's easy to break anyway, so I'm seriously thinking about making RpnCalcPro available outside the market. If that happens, I'll post an update here.
From another frustrated Android user who can't buy apps on the Market - what about selling via Handango? The have a growing Android app base, and are quite easy to use. I have used them in the past for Pocket PC apps.

Very well done! I really like the look and feel of this. I am using on a Droid.
I do not use the programming functions of the 12c, so not an issue for me. Mostly its financial functions.
They have seperate emulators for the 11C, 12C, 15C and 16C, but they also have classicRPN which combines all 4 into 1 app! So it looks like 1 calc, but with 4 different modes.

Another option for a look & feel is ameloconsulting's HP-12C for the iphone
See they also have the stack vars that RPNCalcPro has with Y, Z, T but across the top. You might have some space for the key spacing if you did the same. They've also made the "f" & "g" keys the same colour as a real HP-12C. And they even tried to emulate the sloping keys.
I'll give running them across the top a try, see how it looks.
The other calculator apps have lots of space between the keys, whereas I ran the keys right next to each other to make them bigger. Do any users of the iPhone calculator apps have any comments on how the smaller keys are to use? I have to admit it looks better that way, but I'm worried about usability.
Oh, by the way, programming mode is on the way. Look for it within the month. I'm thinking of selling two different versions, with programming and without. But maybe that will create too much confusion.
