The machine just arrived. The keys work great. The ENTER key sounds a little different on my machine, but that's all.
Outstanding piece of work.
Nitpicking mode ON: Some of the yellow labels (TAN, BST, PRN) are not 100% crisp. Nitpicking mode firmly OFF. In any case, all labels on my machine are an order of magnitude more legible than the ones on some other machines on market.
I am very happy, that can have a 41 with today's display and all the ROMs. But this machine is useful well beyond nostalgia.
Thanks for everybody involved in this project

Just want to brag a bit and advertise this great machine. Got my copy today (SN: 00589). Works like a marvel. Great achievement! Thanks to the folks who made this possible!
Loading modules (MCODE) and programs (FOCAL) is easy and almost self-explanatory. Put SANDMATH into work (thanks Ángel). Let the DMX41 print over IR to an HP82240B.
That's only the first things I did. Many more to be expected.
Thanks again SwissMicros!
Does it have the same memory map? Since it has all those module loaded, I'm kind of hoping that means all those can be active at once, IOW, not having to swap them out to get the combination of modules you want; and !! I was hoping there'd be a bigger memory map that would finally make it more suitable for Forth. The's a Forth module for the 41, but the HP-41 was very poorly suited for Forth due to the limited memory and the slowness of the 41cx's text editor to handle source-code files. (I don't have the module, but I use Forth a lot in other environments.)

Like the SY-41CL, The SM-DM41X basically uses the same OS found in the HP-41CX - which means they use the same memory map as the original HP machine for both RAM and the "on-line" I/O bus configuration (for the lack of a better word). However they both can store a library of modules "off-line" and have ways to swap and configure the "on-line" setup.

(I don't have the module, but I use Forth a lot in other environments.)
As per the FORTH case, since it uses a dedicated buffer in main RAM for all code and dictionary - nothing has changed. At times I've toyed with the idea of writing extensions to it so that X-Mem could be added to that dedicated buffer (I got the basic low-level routines done) but never took the plunge; the ROM has some obscure areas that would need some further studying first.
What I still miss is the possibility a HP-41C port extender over the micro-USB interface. It would be a very big expansion if the old HP-41 devices such as printer, cassette, etc. are still usable. All the CL functionality including the flash should also integrate in the new DM41X.

@Massimo : Thanks!

The interface is micro-USB, not USB-C.

SwissMicros has the SDK for the DM4x calculators posted on GitHub:

So it should be possible to interface an embeddable FORTH implementation to the display and keyboard. Then you would need to add the FORTH word definitions for the calculator functions.

Thank you for letting me know. Please try out the link and let me know. I'm pretty sure the OSX version is not working.
The amended link in the original post works now. Thanks.
Can one use a .raw file created using the HP-41CX emulator on the DM41X (after copying it to the machine)?

Yes, assuming it's a 'standard' .raw file (I'm not sure which emulator you are referring to, but most support the same format, so very likely it's a YES), both import and export of individual programs is supported.

Its the one based on Warren Furlow's work. The latest is version 9D by Christoph Giesselink.

Yessir, you should be all set to easily import it into a 41X and go, go go!!
My DM41X has been delivered today.
First visual impression: great keyboard feeling and yellow/blue button painting solved.
Finally a keyboard that works, it took SM several years to solve this issue, but they nailed it.
The system keyboard test must be revised though, you have to be a seer to find the right key sequence to press.
I hope they will eventually sell a DM42 & DM41X beta replacement keyboards.
I am a little lost on some of the options, but that is to be expected.
I was very skeptical, but SM prove me wrong and I am very happy about it.
Great machine overall, final product was worth the effort, congratulation.
Thanks to: Michael Steinmann, David Jedelsky, Godwin Stewart, Robert Prosperi, Ángel Martin and all the beta testers.

Serial#: 0866 arrived in Carmel, IN USA (suburb of Indianapolis) in 8 days after shipping from SwissMicros. Nice job! I'm very pleased with the key response. The ENTER key is a bit "clicky" sounding, but registers only one press when depressed and released. Slight defect in the printing of the second "E" of the ENTER label, but will try to ignore my OCD about the small, missing white pinpoint artifact. I'll be interested in seeing how well the on-key labels hold up over use and time.
I'm glad I ordered a production DM41X model. I would like to retrofit my beta DM41X with the "new" keyboard, if and when available. Now I've got to figure out how to play with modules.

Just got my DM41X here in MI this morning!
Bottom line: the keyboard, while certainly not as legendary as the 41C (nothing is), is still a huge improvement over the original DM42 design, and is a joy to use. I haven't taken any force measurements yet, but I suspect it comes in somewhere between the HP 35S and DM15L. The keys have a very audible "click", so if you're planning to lay in bed and program by reading light, your spouse may not appreciate the noise.
Mine has a minor printing blemish on "SPACE" under the 0 key, but I'm not particularly worried about it. Most of my HPs have their share of battle scars.
Now I have to figure out which modules to "plug in", in addition to my usual loadout of Advantage, Math/Stat, and Finance... I suppose I should check out the legendary PPC ROM.
Question: is there any easy way to take a bundle of exported .raw program files and convert them into a custom ROM module image?
