I like the circular slide rules because you can never go off scale with them! IIRC even with it being only a 2 inch diameter “pocket watch” size it would come close to a 5 inch slide rule. So every thing you can do on the C and D scales you can do on this one.  :tu:

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.

I fixed the missing picture that showed the 32 digit precision.

I was cleaning the upstairs room and found my Texas Instruments Ti-37 Galaxy solar calculator in an long unused brief case. I thought it was stored elsewhere and was surprised I found it where I did.

A little Leatherman information.

So the oldest item in my office (after me), is my HP-65. Used daily for basic calculations. Card reader still works. Stores up to 100 program steps (the limit of the HP-65). Has a rebuilt battery pack and the serial number dates this one from 1973, so now getting on for 47 years old.
Still prefer the positive tactile feedback from the HP-65’s keypad to anything else this side of a mechanical gaming keyboard.
Quite incredible that this piece of electronics is still working perfectly after all this time. Such a testament to the vision of Bill Hewlett and David Packard.  :salute: :salute:

after 6 months working in France with AZERTY keyboards I'm wondering if the calculators have equally frustrating key layouts to make life difficult.
