If I'm honest, I made the calculators about 6 years ago (and I use them literally every day so they've had a fair amount of testing), but today I released them onto my website on the (astronomically slim
I know RPN calculators are a bit of an acquired taste, but having used them for 25 years, I couldn't go back to conventional (infix) calculators.
No, we just didn't want to ask what is was.......
I did say that I didn't think it would be of interest to other people
... but since you asked....
RPN is an alternative way for calculators to work. In you calculator, if you want to work out (4+3)×(8+2), you probably type "(4+3)×(8+2)=". In mine, I type "4 ENTER 3 + 8 ENTER 2 + ×". Sounds cryptic, but your calculator requires 12 keypresses and mine requires only 9. When you're doing lots of maths, it's a lot quicker (once you've got your head around it).
The basic idea is that you type the values first and then the operator. So 4+3= becomes 4 ENTER 3 +. The + button takes the last two values entered and adds them together.
As I said, it's an acquired taste...
I know if I try to use a modern calculator borrowed from any of the more youthful ones in our office, I cannot work it - they seem to require a different order of input to my old Casio fx451 of 1986 ish vintage. I bought new old stock spare one just in-case it gave up the ghost and left me struggling.I did say that I didn't think it would be of interest to other people

Are they simple enough to make? Could do with some pallet forks for ours.
Easy. If you’ve a CNC plasma I’ll send you the dxf?
