A review of the SwissMicros DM42, a modern clone of the HP 42S. You can buy the DM42 on Amazon using the following affiliate link:
- amzn.to/3fYOF18
In this video I compare the two devices, and walk through the DM 42's basic functionality. I also show an example of a FOCAL program to calculate the fall distance an object falls under gravity and demo this program can be used with the Solver feature. Lastly I talk through how the device's USB connectivity works and do an overall summary.
To find out more about the DM42 check out the following links:

Great video. In what way are the Free42 and DM42 significantly different?

@CalculatorCulture 3 жыл бұрын

Im not sure exactly, but from my limited understanding, the DM42 uses a fork of the Free42 core library, see github.com/swissmicros/free42, as well as its own version of frontend component of Free42 (github.com/swissmicros/DM42PGM) to support the DM42 hardware and DM42 specific features as described in the user manual. technical.swissmicros.com/dm42/doc/dm42_user_manual/

I held off on getting mine until now (it arrived yesterday) because of the keyboard issue. Time heals many things. :) First impressions: Keyboard: Keys feel great. No mushiness, good travel, and no bounce issues (looking at you HP 15C LE) Build: Has quite a bit of heft to it. And the calc feels very sturdy. Display: It appears to be an E-Ink display and it is fine for normal lighting. Font is very crisp. Won't be impressing HP Prime users anytime soon. Actually very pretty. Speed: Yes. kzfaq.info/get/bejne/epNinrCq0bydnn0.html for a comparison. Mind you, the DM42 is running in slow mode. Battery: CR-2032 non-rechargeable. Storage: 6Mb. Cons would be: It would be nice if the real estate used up by the "SwissMicros DM42" be taken up by a larger screen. I'm pretty sure that we all know what we have in our hands. The website info concerning flashing the DM42 is woefully out of date, including dead links. Instructions for activating the USB disk included installing a driver (which I couldn't do, and it turned out that it wasn't necessary), to strongly recommending that you backup your FAT first (with instructions on how to do this missing). In the end it was as simple as Activate USB disk from DM42 program SETUP → File → Activate USB Disk or directly from DMCP System menu. (And only then) Connect USB cable from DM42 to PC/Mac computer. Selecting your two files and telling it to flash. Once complete, you will then have to flash the second file before you can use your calculator. The "Save and Restore State" instructions can be found in the serial guide: technical.swissmicros.com/manuals/swissmicros_serial_guide_v1.63.pdf "Save and Restore" is part of the backup plan, I think? A bit late for me, LOL! Curiously the only HP manuals on the site are in German. But I'm sure that I can find the English ones on my own. So far I'm very impressed. I can see it being my everyday calculator. Thanks for the review!

great review... is it possible to access the clock and date functions in your own programs?

@CalculatorCulture 3 ай бұрын

Yes there are some time and date functions from Free42S that are available on the DM42. Eg edspi31415.blogspot.com/2020/12/dm41-and-dm42-self-timing-programs.html

Hi I see that you probably bought it this year? Did they fix the hard keyboard? Cheers

@CalculatorCulture 3 жыл бұрын

Yeah i bought mine at the same time as the DM41X - they have the same key action.

@@julioc4978 apologies for confusion- I meant the latest revision of DM42 has the same improved keyboard as on the DM 41X. Ie. The keys are no longer difficult to press.

If you know of any surveying programs for the 42, could you let me know.

@MattMcIrvin 5 ай бұрын

A peculiarity of the original HP42s is that it appears to be capable of exponentiating matrices with the e^x key, but it's not doing the right thing: it just finds the exponential of every component. (The RPL machines just give up and throw a "bad argument type" error, which is better--if you can't do something, don't tell me you can.) Does the DM42 do something different?

@CalculatorCulture 5 ай бұрын

I don't have my DM42 here at the moment to check but since the DM42 is based on Free42, it would surprise me if the behaviour is different from the HP42S.

@gettheflockoutofhere 13 күн бұрын

My guess is you would still recommend the DM42, given it is more capable and can become a C47, or maybe not. The states are interesting and more functionality is immediately accessible. Thoughts?

Depends on your taste, but it’s still my favourite.
