- 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:

Thanks - I got the math ROM installed from following your video
I am still using my 41CV every day from my college days in the 80s. I don't need one of these, but I want one.
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.
Dear @Calculator Culture, I have ordered a DM42n and am strongly considering purchasing the DM41X if anything, because it comes with the HP Application pacs built into it and as a handy back-up.
As a long-time HP-41CV then CX user from the early-80s, I pined over the memory limitations of the 41C series calculators.
Can you please confirm that loading a Module is as easy as selecting option #4 ("Load Modules") at the 12:54 minute mark of your video?
Many thanks.
Yes it is, assuming the module is already on the DM41X. The DM41X comes with a bunch of popular modules already in the device. For others you will to download them from hpcalc.org and load them onto the calculator via the USB link. It’s all fairly straightforward though.
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.
Very nice! But I'll keep my DM42 which for me is perfection.
It’s hard to beat the DM42
Amazing video!
Does DM41X have native support for complex numbers and for hex/octal/binary?
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?
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
@@CalculatorCulture Is the DM 41X a newer model with more memory?
@@johndistler8037 yeah its a newer model with more memory and the ability to transfer roms via USB
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?
@@newoldbrain Hmmm? Interesting, I have quite large HP-IL loop/s rarely do I need to replace batteries
@@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!
Is it a graphing calculator?
No, it is emulating the HP 41CX which came out long before the first graphing calculator.
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!
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.
@@CalculatorCulture Cannot fault them for making a profit, thank you for posting.
Does this calculator come with a physical instruction manual?
No it doesn't - there is help function on the calculator and an online user manual technical.swissmicros.com/dm41x/doc/dm41x_user_manual/. You can also
If you work your way through the manual of the HP-42, you'll learn 98% of what this calculator can do, and you'll also fully appreciate why the other 2% is so cool.
Please speak louder. I love the content and delivery in your videos, but the cracking of your voice when you speak so low is too much to take.
It's the repeating rythm that I can't stand
I put on the subtitles because of that.
Look at that price... useless...
Yeah it is not cheap, especially since the Swiss franc has been strengthening against the usd, eur etc
@@CalculatorCulture Well, a used HP-41CX is much more expensive. A new HP-35S is cheaper in some countries
