AriCalculator is a home made pocket calculator.

Very nice and great work !.
I like the acrylic cover as it gives a nice feeling in the hand.

There are now more of us (I presented two of my prototypes at the last Allschwil meeting).

On the processor: there are enough to pick from, I still think it does not play a really big role. For example, for my own calculator prototypes I tried in the last 15 years or so he following:
HC68HC11 (assembler)
SH-1 (assembler/C)
H8/300H (assembler)
AVR (assembler)
AVR32 (C)
LPC1769 (C, current)
PIC32MX (C, current)
i386 (Development machine, C, current)
STM32 (C, current)

On the H8/300H I went as far as having a graphical user interface, all in assembler. Wasted work, I cannot port it. That's why some 10 years ago, I decided to go for C. My current HP-Like code base works on several architectures: x86, MIPS and ARM. It is
portable to the point, I only need a HAL and a recompile (yeah it took so long).

Forth is a good choice, you port your virtual machine and should be ready.

The thing in choosing a language boils down to what do you have to achieve: Do you want something like a HP-48 (what I want) or something more like a HP-41 ? so to say.

I think it is time someone (we) work on a case/keys combination .
