Same to you!

Thanks 😊. I’ll add the listing to the video description later today and let you know.

@ many thanks!!!!!!

Just added BASIC listing to the video description - I hope it wows your nephew 🤣

@ I know what I am doing tonight!!!! Thanks!

Was the song Jingle Bells 😂

@@bernard2735 lol 😂😂

I hope you find it 🤞🏻. They go for more than a song these days!

The video description includes links to the firmware and games. Let me know how you go and if you have any issues I’ll try and assist.

Mine uses 3 x N size batteries

Interesting point. I hadn’t thought about that.

I picked up the re-release, the SL-880-N, in Japan last year but haven't opened it up yet. They removed the music functionality but added ability to mute the games sound. Has solar power too.

The original HP-41CX is getting harder to find and they are typically pretty expensive. Even if you have one, many modules are almost impossible to find these days and even if you do, they are also expensive. The PX41CX (like the DM41X) allows you to virtually load a combination of any of the available ROM modules. It's not the same as the original of course, but the PX41CX layout works with my 41C muscle memory and is probably a better option for a daily driver or to take to the office than a rare, fragile, original classic HP-41CX.

It's much cheaper than the DM41X and the display is excellent 🤓.

Nice - me too 🤓. I'm just missing a 41CL but I'm not sure you can get these upgrade boards anymore as the parts are getting harder to find.

@CalculatorClique So where is available this PX4141CX ? Is also SwissMicros?

It's not from Swissmicros. See Alex's website and there should be information and links to purchase there soon, the PX41CX is new. His existing PX models are listed there too - paxer.net/voyager/. I'll update the video description with the PX41CX link when it's available.

@@CalculatorClique well 💙💙💙

The PX41CX page is now available including full specifications and a link to purchase on Tindie as a kit or pre-assembled. See: paxer.net/px41cx/

Sorry, I haven't got back to it yet as I've moved on to other projects. In the meantime, if you've started developing something yourself and have any questions then feel free to email me and I'll answer as best I can and provide code snippets.

Thank you 😊. Python typically runs faster than PPL and CHIP-8 I've ported to other platforms also draws the Pac-Man screen quite slowly so I wonder if this is deliberate and there is a delay in the code. I had to check for and slow the virtual Prime down a lot otherwise it was unplayable.

@@CalculatorClique As someone who had to listen to no end how BASIC was sooo slow, seeing Python becoming so popular is a bit of a head scratcher. But it is great to see some development for the Prime. Thank you! :)

Hahaha 😂 Comments like this is why KZbin comments need reactions 😊

I own many amazing calculators and love your channel. But I just don’t like the prime. Can’t really put my finger on it. Just not my cup of tea I guess.

Thank you, I'm glad you like the channel 😊. I hear you regarding the Prime, I'd pickup my 41C, 48GX or 50g for general calculations before the Prime typically. I'm not exactly sure why either although the RPN is not the same as traditional HP RPN so that doesn't help. The hardware is very powerful but the keyboard print is hard to read (for me) even on the G2. I am enjoying porting Python applications to it though. Waiting for an update to fix a lot of the Python issues.

Hola julián! Eso sería increíble y definitivamente compraría al menos uno! Aunque no aguantaría la respiración 😔.

I'm running version 2.1.14603 on my physical Prime G2 which includes Python support. The current version is 2.14730 which lists fixes for 4 different crashing issues. I didn't update my physical Prime as there were no fixes for what I typically use and some users reported issues updating (although it seems to be mostly related to version C hardware, the G2 is version D hardware). I have updated my virtual Prime (and Connectivity Kit) and it does crash regularly but this may be a virtual only issue. See the following thread at the MoHPC site for more information: www.hpmuseum.org/forum/thread-19845.html

Yes, it should work on an emulator. I compiled it as a standalone binary so no special firmware with builtin libraries is required. I have not tried it myself but please let me know how you go.

@@CalculatorClique thanks, but how would one load it into memory?

I'd have to try it out myself and see. Which emulator are you using on which platform?

@@CalculatorClique I'm using Emu48 set to a 50g on Windows, thanks

Ok, I've just had a look at a couple of emulators and as HP GCC compiles to ARM code it won't work on emu48 (as it doesn't emulate the ARM processor, only the Saturn processor). You will need to use the emulator x49gp to run HP GCC programs. I was not able to find binaries for x49gp so you will have to build it yourself and it only supports Linux and MacOS so you would have to setup a Linux virtual environment under Windows.

Aapaka bahut-bahut dhanyavaad 😊

Yes, the module supports the 850p as well. Check the links in the description where the maker lists all models supported. Note, I’ve only tested on my 880p and VX-4

That's great if the contrast is good enough for you. The blue on green display is easier to find and cheaper than the black display. Also, the black display doesn't have double-shot injection molded keys (although some of the blue display versions got the painted keys before they went to the black display).

I don't have a flashable 12C and so don't have the firmware for it either (as I haven't needed it). There are also a number of different versions available so you would have to make sure you had the right version. Have you looked at the 12C development kit? It includes a firmware file and might be the correct version but check the documentation first to see if it matches your hardware (CPU etc). Please let me know if you find a solution. www.hpcalc.org/details/9554

Yes, they are a high quality, modern incarnation of some of HP's best calculators 🤓. Closest thing to the well known HP key click I've seen.

Let me know how you go and if you have any feedback on the keyboard layout. There could be some inconsistencies too as I did it all in one pass/update. Thanks 😊

What’s the key combination to open the dmcp menu?

Looks like it (accidentally) followed the DM41X USR key so should be on SHIFT F5. It probably should go on SHIFT 0. Note, this menu is cutdown and includes enabling USB drive mode. To get to the full menu you need to exit FORTH with BYE. Let me know how you go.

Да, они не дешевые. У меня есть только один калькулятор Swissmicros (DM41X). Однако они представляют собой высококачественную современную копию некоторых классических моделей HP.

Overall the DM42 (and DM41X) run about 3 times faster when powered via USB instead of the internal battery. So, for example, N-Queens and the hat plot take about one third the time to run compared to the demo.

@@CalculatorCliqueThanks. I have to find a FORTH for the Prime :) I think there is one for its micro-Python.

I’ve ported a Python FORTH to the Prime. Checkout the video on this channel with download and install instructions and a demonstration. Includes graphics too. Let me know how you go.

@@CalculatorCliqueThanks is that on the later generation Prime? 2.5 seconds was a good bit slower than the Swiss Micros.

Yes, it’s a Prime G2 which is the latest and fastest hardware version.

I believe it only works on the original. The subsequent 15C versions all run within an emulator. Let me know how you go.

The keys feel the same to me (discounting age/usage). One thing to note about the later high contrast (black) display models is that they had printed keys instead of the double-shot injection molded keyboards of the earlier models. It is possible to transplant a black display from a cheaper donor (eg 39g) to all 48 models but as the 48 series was not designed to be taken apart/repaired this is a significant and high risk task.

I find Forth easier to remember and pickup again after a break compared to, say, RPL. Forth also runs on pretty much anything.

Try turning on captions and slowing the video down a little. If you have the first ROM version you can automate the process. I use my own voice in later videos 🤖

Thank you 😊. Is there a simple test I can perform to check as this is not a discipline I'm familiar with? I probably should just upload a copy of the module somewhere so people can review it and test it.

Thank you 😊. The board installation and operation instructions are contained in the CalCom.zip download from teenix.org. There are a number of PDF files included detailing how to install and operate the boards (Classic, Spice, 67 and 97) and how to use the CalCom communications software.

@@CalculatorClique thanks for your quick reply, I will have a look, Cheers

The VX-4 uses an 8-Bit Hitachi HD61700 CPU, the FX-890P use a 16-bit Intel 80186 compatible CPU so machine code programs are not compatible between these two devices. You would need to look for FX-890P specific machine code games / programs.

@@CalculatorClique I had forgotten that they had different processors. :)
