Next to the extended early typewriters exhibition was also an extended calculator exhibition. Lot’s of mechanical devices from an early age, cash registers and other counting devices. Unfortunately I couldn’t make any pictures of them, since it was rather busy with all the people wandering around. Luckily I did find this one a bit further down the aisle:
Do you notice the display in the back? Time for me to ‘ooh!’ and ‘aah!’ again! Telephones! One day… I will own a couple of these too.
The next part was about IBM punched card machines. I didn’t make a lot of pictures here either, since I’m not really a fan of those machines knowing why these machines were such a success during the 40’s. But here is one of the small ones:
This one is rather special though, and immensely big too! This is a Jacquard machine and you can read more about it at the Princeton website. The Jacquard machine was the first machine to use punched cards to control a sequence of operations. Rather impressive.
Now this is the part where we began to get tired and hungry after walking around for two hours. Luckily we found a ‘hidden’ exhibition that got us very excited again.
Can you guess it already? No? Maybe this picture will help you.
Clear enough? Thought so. It’s Cryptology time!! Whoohoo! It was a very small exhibition, also some kids were running around on a scavenger hunt, so I couldn’t make an overview picture, but… I did get to take pictures of the machines itself (which were all from the NSA’s collection according to the description notes). If you want to find out more about these machines, visit the online cryptomuseum.
