Museum of Pocket Calculating Devices

My dream is to one day own a Curta. I want to find an algorithm to approximate pi, one crank at a time. I had a chance to hold one at a vintage computer festival once. Smaller than I expected. Truly pocketable.

I just had a thought. Why hasn't a Curta simulator come out for the Playdate? I guess I am cursed with creating it

I was really looking for watch calculators.

I have 2 listed: HP-35 and HP-41CX.

Still use an HP-11c.

Will die on that hill defending RPN!

I have a few pocket computers not on that page. I guess I have a new option where to donate them if I ever decide to part with them.

As the old joke goes:

"For your birthday, I wanted to get you a pocket calculator ... but then I thought you'd already know how many pockets you have."
