I was pleasantly suprised to the forum upgrade. I am not a collector but an avid user. I have stumbled across this site searching for android application & calculator emulator I could load on my phone. I have to admit that I have learned a lot more about my hp35s and the other models. I am now spending my time reading all the post on my tablet and having a relaxed cup of coffee. I have dusted my old palm loaded the hp42s & hp41cx emulator and now tinkering with some of the programs in the library. I also searched for a possible second hand hp42s and nearly fell backwards when I saw the price $239 on ebay. Surely this can't be right, I thought. But there it was, I became a little nostalgic. I should have kept mine instead of selling it so many years ago. RE: I am a new member - hp35s owner - Paul Dale - 01-07-2014 08:53 AM Find yourself a WP 34S.

Funny thing you should mention that, since the FEDEX guy rang my doorbell about 25 minutes ago, and guess what I found inside the box. RE: I am a new member - hp35s owner - Jean-Marc - 01-07-2014 09:00 PM WP34s the homebrew calculator. I saw a post yesterday on this forum and thought that it was discontinued or abandoned. I tried the search on the forum again but it timeout. If this calculator does get sent to Australia I might consider one. Are we talking about good battery life with a similar software layout to the hp42s. I will download a manual or something along these lines maybe there is a youtube tutorial. I am getting curious about this.

I am getting curious about this. Start with the pdf manual: http://sourceforge.net/projects/wp34s/files/doc/Manual_wp_34s_3_1.pdf/download Look here for more: http://sourceforge.net/projects/wp34s/ Of course this calculator gets sent to Australia. Please see p. 2 of the pdf manual for suppliers. d:-) RE: I am a new member - hp35s owner - Jean-Marc - 01-08-2014 03:31 AM Thanks, I just realised by the name that this is your baby. Great work, this is a powerful calculator very impressive and covers almost everything. It's only restricted by the hardware it seems. Shame for the soft menu this was a nice touch with the hp42s. I also like the way you could do a simple cross product with the hp42s. I skimmed through the manual but I could not figure out how to do the same with the WP34s calculator. It could probably be achieved by a program like the one written for the hp35s. I have to do more research. If the WP34s gets a waterproof casing this calculator would suite engineers and riggers in the field. It would be a great asset. Some petrol refineries have restrictions such as no mobile phones, wifi devices so you are left with just a good calculator pen and paper to resolve problems. It can be a good backup tool for field work and for less than$100.00, brilliant. Keep up the good work ! RE: I am a new member - hp35s owner - Dave Frederickson - 01-08-2014 04:22 AM I'm looking forward to the WP 43S.

From HP 35s - my first thoughts: X001 LBL X X002 ABS X003 CLx X004 LASTx X005 RDN X006 RDN X007 [ [0,[0,0,-1]*REGT,[0,1,0]*REGT]*REGZ, [[0,0,1]*REGT,0,[-1,0,0]*REGT]*REGZ, [[0,-1,0]*REGT,[1,0,0]*REGT,0]*REGZ ] X008 REGZ X009 RDN X010 RTN Arne Halvorsen created the Euclid Pack - The Geometric Calculator. Thought that might be interesting to you. Quote:I skimmed through the manual but I could not figure out how to do the same with the WP34s calculator. Since the WP-34S doesn't provide a 3D-vector type that's not possible unfortunately. You could use the 8-element stack and write a program for it.

There are more parents, however: At least 50% of the fame should go to Pauli, your fellow Australian. And Marcus made a very good job in bringing our baby to birth. And Pascal and Neill and Eric and ... (see WHO on the WP 34S and the Welcome chapter of the manual). d:-) RE: I am a new member - hp35s owner - Jean-Marc - 01-08-2014 09:13 AM My congrats to the team, I just downloaded the ios emulator which is based on your work / team. The keyboard is different from what I am accustomed. I was surprised that it only took me about 15 minutes to figure it out. It is intuitive and the keys are grouped appropriately. I also read that you have another project the wp43s as another challenge. I think you are on the right track. If you incorporate soft menu and it is enclosed in a robust case this would become a gem. All my praise you all deserve it and don't be modest I can tell that this is a lot of work. I will be keeping an eye on this project.

Showcasing some of the feature of the new wp34s calculator with examples. Nothing too complex vector arithmetic, polynomial solver etc. Would this be okay with the original founders? This is just a suggestion that I am submitting to everyone knowledgeable and reading this post. I would enjoy watching it. I am currently using the ios wp34 emulator and it is usually not quite the same as the real thing. For example the Free42 for palm 1.4.71 has a bug where if you add 1+2+3+4+5 you get 20 instead of 15. However the Free42 for ios doesn't have this bug.

The calculator was set to engineering display 0. So as you get to 10 and add 5 it displays 20 then 30 and so on. Once you know the rule it does make sense. Maybe not a bug but a feature of engineering display 0.
