A review of the SwissMicros DM41X, a clone of the venerable HP 41CX.
You can buy the DM41X on the SwissMicros site at:
- www.swissmicro...
In the video I talk through the basic function of the calculator, demo its display modes and its extensions. I also show an example of a keystroke program and the loading of modules.
For more information about the DM41X, check out the SwissMicros site:

For more information about the HP 41C check out the follow links:

Thanks - I got the math ROM installed from following your video

I'll probably remain very tempted to get one for the rest of my life ;)

I want to give him an upvote for the review and a down vote for the temptation.

I didn't last. After several weeks, mine is on a delivery truck somewhere in Manhattan headed to my apartment right now. Resisting the urge to leave work early due to "illness" (calculator fever?)

I am strongly tempted, but I no longer have the need.

Very nice! But I'll keep my DM42 which for me is perfection.

It's a shame Swiss Micros failed to implement HP-IL with this device. It is HP-IL that made the HP41 series a 'system' and that differentiates it from all other calculators. The HP-IL is fun for amateurs and provides real professional capabilities. The community has also created interfaces that enables HP-IL to be connected to PC's and even puts HP-IL over WIFI! I think Swiss Micros made a big error there.

I think these days it would be better to put Bluetooth Low Energy (BLE) in there - it is similar in concept and capabilities, but wireless and also much easier to get parts for these days.

HP-IL means being able to drive a 100 ohm 100 meters transmission line. It also has requirements on galvanic isolation. The former point makes it impractical with a small battery. The latter calls for magnetics (transformers), while they can be miniaturized, it's still a serious complication for a calculator in that form factor. And, sincerely, how many HP-IL instruments are still around?

@@kingofcotham9999 Interesting! Out of curiosity, how many of them run on a CR2032, with a capacity of 220 mAh? There's also a commercial point of view: SM caters for a niche (RPN lovers) of a niche (people still using a calcualtor). HP-IL users are probably a niche of a niche (test instrumentation user). That's be catering for a RCL "niche" 4 y^x But I can understand your point.

@@newoldbrain Ha Ha yes! Any IO would have at least given a chance for writing an interface especially now that virtual HP-IL is available. Most of my HP-IL stuff runs off re-chargeable batteries but the HP41 uses ordinary alkaline ones and they last a quite long time (> 6M)! I also have a plotter (mains) on the loop great fun!

Would like a video to do Matrix, Integration, Solver, and TVM functions. I can't find any manual that shows how to do these items.

Hi Jay, I made another video about the HP Advantage Pac that includes those functions.

@oldtechie6834 3 жыл бұрын

Does DM41X have native support for complex numbers and for hex/octal/binary?

@CalculatorCulture 3 жыл бұрын

Yes and no. Advanced functionality on the 41C family came in the form of pluggable ROMs. The 41X comes with the original HP pacs loaded on it, but you need to "plug in" these via the Modules menu. Complex numbers and base functionality are available in the Advantage pac (which I have a separate video on). The functionality isn't as user friendly as say on the HP 42S/DM42.

I had an HP 41C with a math pack that I bought in 1982 and used through the last 3 years of my engineering school. I foolishly gave it away after passing my state engineering exam. I bought a Swissmicro DM 41L hoping to get the same thing but there is no math pack. Is this DM 41X what I am looking for?

@CalculatorCulture 3 жыл бұрын

Yes. Unfortunately the DM 41L only has a small about of flash memory and it's not possible to load extra ROM modules on it. People have requested the Advantage ROM be built into the firmware but I dont believe there is enough free memory. There is a thread about it on the SwissMicros forum forum.swissmicros.com/viewtopic.php?t=421&start=10

Why doesn’t this company offer a standardized hardware design and sell the appropriate software with its corresponding overlay. It’s 2022, get with it!

@CalculatorCulture Жыл бұрын

Yeah the idea of SM selling a blank calculator has been talked about a lot in the community. I think they see themselves as a hardware company though and that would be quite a different business model. I’m just glad they are do what the do and are giving us great devices.
