RE: Yet another DIY RPN calculator

(Btw: This is essentially the same as if you press a "cos" button on a calculator: It makes the calculator run a program). This is much much easier than to build a new calculator. So I do not understand your motivation to build yet another calculator. Sure it's easier, but still by far not as flexible as a custom firmware. E.g. I doubt it is possible to completely redefine the whole context to enable all functions to operate the values with uncertainties and to customize the display output such as to conveniently display such values. Possibly a way to go would be to buy the SwissMicros machine and make a custom firmware from scratch, but then I also wanted to attempt to make a better keyboard. Not sure it ended up being any closer to the original HP, but at least it's soft and not clicky (I've used the softest tactile buttons I could find in the catalogs). Finally, and maybe most importantly, I believe you understand that the motivation does not need to be completely rational |
