I'd also like to move the statistical distributions from keystroke programs back into native C -- faster predominantly but also potentially a little more accurate. I don't have a time frame for completing this and it will require a fair bit of stabilisation. I'd also like to try to find a faster algorithm for logarithms which are a bit of a sore point on the 34S. - Pauli |

Jose, It would be great if you could test the QtGui version. I've created a build that you can download from my site: http://jmcameron.net/wp/wp31s_qtgui-2014-03-28.tar.gz This is a 64-bit build done on Ubuntu 12.04. It may work on other Linux 64-bit builds with appropriate Qt libraries installed. You can get an idea of about the Qt issues from this README file: http://sourceforge.net/p/wp34s/code/HEAD..._QTGUI.txt I added a dialog that shows the keyboard shortcuts for the QtGui version (under the QtGui help menu): Note that many of these shortcuts are adapted from the Windows emulator, but there are a number of differences. The windows gui can use the Control key for the [f] shift, but the QtGui emulator is not set up for that and uses the Tab key instead. The tar file contains a brief README file that tells how to install it. Enjoy! -Jonathan |

RE: WP 34S --> WP 31S
Thank You, Jonathan!
I will have a try, once I setup one VM running Ubuntu. By the way, thanks for your and the other contributors posts on the serial cable building thread here (very useful info - I ordered the components, just waiting for delivery now...): http://www.hpmuseum.org/forum/thread-183...gle+switch Jose Mesquita RadioMuseum.org member |

The QTgui calculator seems to run normally under Ubuntu, now it takes time to play with it Is there any test procedures to follow, or one can just play at will? I can't wait to have the components delivered so I can start building the cable and start doing some testing. Jose Mesquita RadioMuseum.org member |

Thanks for your information, Pauli! I'm preparing myself to build a WP-34S (late arrival...) and was curious about this new 31S project. Maybe the 34S project can benefit from some of the improved algorithms created here for the 31S? Jose Mesquita RadioMuseum.org member |

RE: WP 34S --> WP 31S
The 34S lacks the free memory space for the improvements, so they are unlikely to be ported across.

RE: WP 34S --> WP 31S
We have integrated Bit's ydisplay mod into the WP-31s code. Marcus has built a version with the following options enabled:
* INCLUDE_YREG_CODE (shows Y in the upper display area) * PRETTY_FRACTION_ENTRY (switches to fraction display mode instantly when a second radix is pressed) * RP_PREFIX (polar y-register prefix) If you would like to try it, the windows gui and the flash image have been rebuilt at: http://sourceforge.net/p/wp34s/code/HEAD...hes/wp31s/ We would like you to try this update and let us know if you encounter any issues with it, or just like it, please let us know! If you want to test the QtGui version, I have a parallel build on 64-bit Ubuntu 12.04 that I can make available for you (PM me). -Jonathan |

Considered it tried, I like it! I am hopeful that Eric will produce overlays so this can go into production. Only one comment so far on operation. Perhaps UNDO is a work in progress, but seeing as how this is the first appearance of such a function on an RPN calculator, I had to try it. I'm not quite sure if it operates exactly as I would have expected. For example, if I do 1 ENTER 2 +, then UNDO, I would hope to get a 1 in y and a 2 in x. Instead, I get a 1 back in both x and y. If I do 1 ENTER 2 swap swap (so that 1 is in y, 2 is in x and stack lift is enabled) + UNDO, I do get 1 in y and 2 in x. I can see that in the first case, prior to the + operation, technically there was a 1 in both x and y as the 2 had not been entered yet. But I believe that classically speaking, as soon as you hit the +, the 2 is supposed to be entered into the x register, so the state of the machine should be as in the second case, i.e. 1 in y, 2 in x and stack lift enabled. Hopefully my description of the actual and desired behavior is clear. Please don't take the above as criticism, overall this is really great work. Dave - My mind is going - I can feel it. |

RE: WP 34S --> WP 31S
Guess I didn't think UNDO through fully
The analysis is correct. In the first instance UNDO is undoing the + operation which includes the command line parsing and X replacement. In the second, it is still undoing the + operation but here there is no command line parsing taking place. Although the current behaviour is surprising, it seems like the right thing to do in light of the case of 1 ENTER UNDO. The ENTER clearly must be undone completely. Likewise, 1 FILL UNDO. - Pauli |

I suspect we'll get some suggestions as to how UNDO should behave....

RE: WP 34S --> WP 31S
That's what I've written in the manual about UNDO:
If you have erroneously called a wrong command, just press UNDO to undo it. This command will restore the stack and all other registers exactly as they were before the last command was executed. Now we only have to talk about what is a command and what's not. The usual monadic, dyadic, etc. functions are easy. A plain numeric entry (pressing some digits, even including radix marks and EEX) isn't a command IMHO. Addenda: What about <- ? Shall be no command unless executed as CLx. Sigma+ ? Shall be reversible by UNDO though there's no pressing need since Sigma- exists. ENTER, FILL, CLALL, RESET ? Shall be commands. d:-) |
