Old Typewriters and Calculators

Hello, here you can find a collection of old devices, typewriters, calculators, computers, cyclostiles, and other devices.

There are also many documents, and videos about these devices. You can download freely the documents. But if you put a like in some of my YouTube videos is appreciated. Thanks.

I upload many of these document every week. But I have many of these, and I have to scan each, so it will take many time. But in the end will be a couple of thousands. Hope to finish soon!
