I had wanted an HP 42S for a long time, and I finally got one (about 6 months ago, but have been to busy to play with it.
one of the most powerful non-graphing calculators that HP ever made. has over 600 features according to HP and is a sought after model by some engineers still to this day.
if only this had a better screen, and USB connectivity for saving or adding programs and data.

and just like that Swiss Micros made an awesome calculator
the DM42.
yes, I had to have one.
one of the really cool features is the saved states of the calculator that can be switched quickly.
EE is the Electronics Engineering, daily is just my normal usage, and I plan to build a financial saved state.
by having switchable saved states, I can load programs, settings, views, etc for a specific function, and then have the same categories of settings for other uses. typically people have all of the programs they use loaded into the calculator, and just call upon what they need at that time. the nice thing about the save states is when I want to to something like financial work, all of the other programs are not cluttering up the lists. The settings such as 2 decimal places are set, and maybe the larger font, are set.
then once I am done with financial work, I switch back to daily and all of my programs and settings are back.
how is the accuracy? IEEE 754-2008 quadruple precision decimal floating-point, which consumes 16 bytes per number, and gives 34 decimal digits of precision, with exponents ranging from -6143 to +6144.
here you can see the x Register has 3.14159265359, and at the top is what is shown when I tell the calculator to show the full value.
the screen is beautiful! very clear and crisp.
the power off state of this calculator displays a type of wallpaper as seen below. you can pick and choose the ones you want and it will cycle through them with every power off action.
the calculator is very fast, and even faster when the USB is connected to a computer (faster clock cycles)
USB allows the saving or adding programs, and other data types including save states. the EE save state I got was a single download that I added, and now i can operate just like the person who spent the time making all the configurations for that save state.
The DM42 runs the free42 emulation software that was customized. new firmware is available periodically and is a simple procedure to update the calculator.
