Here you will find a wealth of data I have collected over the years on general calculators, HPs calculators, TIs calculators, and on my all time favorite mechanical calculator, the CURTA .
I recent years I have become an expert with the amazing Curta calculator. And it's mechanical not electronic! But it represents a final ultimate, state-of-the-art achievement in the mechanical world before the electronic calculator revolution took over and over night obsoleted all mechanical machines. Interestingly the Curta held on for many years because it was so popular among road rallyest and surveyors.
I do collect and study the manufacturing variations of the two models of the Curta calculator. My two exploded view Curta posters are wildly popular around the world and have been featured in museum displays and displayed in the halls and offices of NASA.
