Something comparable to an Arduino Due could probably handle it just fine (though without the many mega/gigabytes of program space that the iPhone version affords you).

The LPC1115 ARM micro-controller used in the DM-41L only has 64KB of Flash and 8KB or RAM. I would have thought porting Free42 to that controller may not be possible. I wonder if they are using a different controller for the upcoming DM-42L?

from Michael's e-mail:
It runs on a single CR2032 battery. The total current consumption of the ARM Cortex-M4 CPU running at 26MHz and its LCD is less than 3mA, but most of the time it's idle consuming only about 130uA.

Intel® Decimal Floating-Point Math Library, IEEE 754-2008 quadruple precision decimal floating-point, 34 decimal digits of precision, with exponents ranging from -6143 to +6144.

Whoa!
