Disregard - I figured it out after looking through the wiki a bit more under SDcard operations. I was looking in the command reference list.
Correct command was: "BACKUP1" SDRESTORE Once I restored, I was returned to the state I remembered. The menu was even in a mode that listed all the SD commands. Now I am trying to figure out how to get back to that one! :-) |

One more thing to add - although I was able to create the SDARCHIVE on the calculator, when I attempt to use the USB archive tool on the Desktop app, I get a USB communication error.
I will try to find some of the USB power saving issues mentioned before and see if I can fix that. Thanks! |

Did you just try to recover your backup using algebraic notation? that won't work on newRPL, sorry. If you don't like thinking in RPL, just think of it as "object oriented": then pile your objects on a stack, and operate on them :-)) EDIT: Glad you found the way of the Reverse Polish Elders...

I guess I was misled by the doc about the 39g+ supporting NewRPL, but given how uncommon this calculator seems to be and how fast it got replaced by the 39gs I can totally understand that the doc was written this way. I got my 39g+ on Ebay for $7 a few weeks ago and my 39gs as well for $20 (although the 39g+ costed $20 shipping) and I find myself using the former more often than the 39gs but I guess I'll use the 39gs instead for NewRPL. Perhaps those were the physical differences, but it would appear that there may have been some differences in the firmware which could negate some of the similarities. It's possible that the chip which holds the firmware could be physically flash rather than mask ROM, but I don't think the firmware provided any way to modify its contents. For example, the boot/sefltest mode in the 39g+ I have in front of me only has one menu option, Code: 1. SELFTEST Perhaps it might be possible to modify the boot code and introduce a flash upgrade feature, but it might need to be accessed via JTAG or some other equivalent low-level interface. I haven't been brave enough to try to open up the case to see what interfaces might exist to even attempt to go down that road. EDIT: Similarly, I also have two first-release HP48gii units (3-cell battery compartment), and they also don't offer a flash upgrade option in their boot/self-test mode. |

I know they originally didn't provide firmware updates but if the hardware was the same you could in theory use the bootloader of a 39gs to replace the bootloader, via JTAG as you said. Same with the 48gii, IIRC it was just limited in software so a hardware solution should enable you to do it. Probably not worth the effort, though, as you'd pay more for a JTAG adapter than for a 39gs that does allow firmware replacement. EDIT: As a wild idea, a program coded in ARM assembly could be transferred to the 48gii via USB and executed that could take a hex string containing the boot loader and write it to flash. If you like to live dangerously of course. EDIT 2: Nevermind, I just read that model had no USB either. |

Hi Claudio,
is it possible to install newRPL on my HP50g and get HPGCC (c programminig) working? Ralf /41/48/ |

All you do is download the source code and add your own library to it. What you won't see is the incredible speedups you saw when going from userRPL to hpgcc. NewRPL has room to be optimized, of course, but is not exactly slow so coding in RPL vs coding in C will give you only a small speed increase, if any. |

Navigating through sub-menus
Hi all,
Hi Claudio, The WikiNewRPL explains how to navigate in sub-menu. But i dont understand this part : Code: "To go back to a previous menu in MENU 1, use RS-M key. To go back to a previous menu in MENU 2, use RShold-M. The last 8 sub-menus are remembered by the system, so it is possible to use this key to go back multiple times." The 'M key' is the STO key in the NewRPL keyboard template for HP50g. I think I missunderstand something. EDIT : Oups ! The problem was the user. It works fine I use both classic HP50g and newRPL HP50g and sometimes I confused myself between the two. |

Sorry for this basic question but I can't find any precision for using the ASNKEY function. Is it documented somewhere?

Hi, Build 1510.
Code: (100,∡45d) →RECT The pb seems in the ASIN and ACOS functions.I use , as fractionnal separator in my setup. |

You've found a display rounding bug. You are set to DMS degrees, and the angle is being displayed as 44 degrees, 60 seconds. Clearly I need to work on that rounding... The good news is the issue is display only, calculations are not affected at all.
Thanks for reporting! |

RE: newRPL - Updated to build 1510 [official build remains at 1487]
Hi Claudio,
I think there is a bug (at least a different behavior) in the CRNM command with vectors : CNRM Type: Command Description: Column Norm Command: Returns the column norm (one-norm) of the array argument. The column norm of a matrix is the maximum (over all columns) of the sum of the absolute values of all elements in each column. For a vector, the column norm is the sum of the absolute values of the vector elements. RPL : [ 1 2 3 4 ] CNRM -> 10 newRPL : [ 1 2 3 4 ] CNRM -> 4 |

RE: newRPL - Updated to build 1510 [official build remains at 1487]
If anyone is interested, I may be offering overlays for sale for the 50g (I already have this one done), and soon for the 39gs. I may look to see if the same overlay can work for some of the other compatible calcs in the future, but I will work on the 39gs first (since I own one).
See this thread for more info: https://www.hpmuseum.org/forum/thread-20113.html I am attaching a pic of my 50g with the overlay installed. The only thing I am waiting on is to confirm that the new vinyl material I use as the base layer will stick better than the recent ones I used. (The key labels had a tendency to lift for some of the non-RPL calcs like WP31S/34S.) I just got some new material and installed overlays on all the calcs and I am waiting to see if the adhesive is performing to my satisfaction. I will be posting updates in that thread as I move forward! Thanks! |

Excellent! .I'm interested in an HP50g overlay and an HP39gs. Rather a question for Claudio: why not associate the following keys: NUM.SLV, MATRICES, STAT etc. ? Is this planned for future versions? if so maybe the overlays should show this in anticipation? Idem for Integral key -> NUMINT If I manage to do videos with the real calculator correctly, I will do some tutorials on the newRPL. I don't want to do them with the PC version because it's far more easy with fingers lol |

RE: newRPL - Updated to build 1510 [official build remains at 1487]
One thing to keep in mind for these overlays. I would consider the HP Prime version to be somewhat experimental or preliminary ("work in progress"?). There are a things that I think could be tweaked in the layout. One example is that there are two keys assigned the <<>> entry.
I'm not sure how much time Claudio has had to consider this stuff. |
