Sorry I didn't clarify. It's a large paper, so anything would help, specifically though I am focusing on stuff in the 18th-19th century (and really early 20th). Thank you! Also, that's cool, my father worked with some of the early punch cards also, when working as a professor, though I think that was a bit later (though punch cards were around, I think my dad used them when they were a way of coding, that was read into electronics).gjonesy said:

Thank you, though I have already tried googling many of those (though I'll try the two I haven't being the bomb sight, and antikythera). Do you know of any specific places, or resources that tend to hold diagrams for them?Nidum said:
Weren't those in the mid-20th century (I don't recognize what you mean by organs, but the others I recognize)? For the project I am doing I can't use anything after the first world war.Nidum said:

Unfortunately, my project is primarily written (it is actually a history project, but rather open in subject matter), so I don't think that would be possible.Nidum said:
Is there any data base that sorts them with dates? I know the US trademark office site, but it gives all of them (and all related laws), and even under mechanical computers, it doesn't give me enough options to practically organize it.gneill said:
I'm not aware of such. Which of course doesn't mean it doesn't exist.Dembara said:
I can't seem to see all the info on it (or I am just looking over it), could you give me the name and/or the full citation? Thank you! It looks really useful.Nidum said:
I found this site which provides the patent numbers, and images of them.gneill said:
An early mechanical/analog computer is a type of computing device that was developed before the invention of modern electronic computers. It uses physical mechanisms such as gears, levers, and cams to perform calculations and solve problems.
The earliest known examples of mechanical/analog computers date back to ancient civilizations, such as the abacus used in Mesopotamia and China. However, the first programmable mechanical computer was invented in the 19th century by Charles Babbage.
Data input in early mechanical/analog computers was typically done manually by operators through the use of dials and knobs. Output was often displayed through the use of gauges or physical printouts.
Early mechanical/analog computers had limited storage capacity and could only perform specific tasks for which they were designed. They were also prone to mechanical failures and required skilled operators to use them effectively.
Although early mechanical/analog computers were limited in their capabilities, they laid the foundation for modern computers by introducing concepts such as data storage, input/output mechanisms, and programmability. Many of the principles used in these early computers, such as binary arithmetic, are still used in modern computing systems.
