Vintage III - Mechanical Calculator

I have been busy making a detailed audiovisual archive of the below mechanical calculators at The National Museum of Computing, Bletchley Park as part of my project The Imitation Archive.

I am going to be working on creating audiovisual archive material for the next month. This is my first post. A series of simple images of mechanical calculators, all of which have a similar aesthetic to them, by and large but from different manufacturers. A variation of a theme.

These are common devices used pre-computing. They are the original data processors. Moving on, I will begin to investigate the calculation power of electronic counting machines (early computers) and will continue to post audiovisual material as I progress through the collection. Facit - Mechanical Calculator Contex - Mechanical Calculator Brunsviga II - Mechanical Calculator Brunsviga - Mechanical Calculator

The Imitation Archive is a residency project with The National Museum of Computing, with support from The Arts Council England, The British Library and Birmingham Conservatoire.

High definition audio and further commentary coming soon.
