Small adding (Videos)

Virtual Museum > The early ones > Simple Adders

In a separate page I was showing pictures of the Small Adding machines.
In this page, I will show you 2 videos:
- The first one is a demo on how to use the Resulta 7 adding machine
- The second video is a family portrait of different adding machines from a similar period, all using wheels
