I just received my DM42 from Switzerland! Made by SwissMicros, this unit has an SN of 835. If you are not familiar with this RPN calculator manufacturer, I would describe in one sentence what they do: take a classic Hewlett-Packard calculator, improve its design, et voilà! The DM42 is an HP-42S equivalent. It runs the free42 software stack. The quality of the hardware is simply remarkable. The build and materials’ quality is impressive. Great job SwissMicros! The display is astonishing (the pictures are hardly representative) and is close to what an e-ink display is. Add a lot of new features, extensibility, and you get very close to the perfect RPN calculator! Note that SwissMicros offers other models, each of them quite innovative. For example, I also own a DM41L. This calculator is an HP-41CX equivalent in the form factor of an HP-15C!

francois P yeah, a really nice one!
Funny, I also bought a SwissMicros DM42 calculator. Mine has serial number 00859. As already mentioned by Jamel. The quality and the first impression convince me very much. I can even print on the 822408B thermo printer with the DM42! Since I have a real HP 42S since 1990, I can now compare both systems directly.
Lorenz Born thank you for sharing your experience. I would be very interested to have the opinion of a 42s owner!
For the sake of completeness, a pic of the 41cv and the DM41L.https://plus.google.com/photos/…
