Tech Tangents | 1957 - Bohn Contex 10 Mechanical Calculator In Depth Look @TechTangents | Uploaded June 2019 | Updated October 2024, 9 hours ago.
This is such a cool little device, an all mechanical calculator with a keypad input that supports the four big functions. This thing rocks!

After going back and re-reading the page I mentioned that used foam to repair one of these ( csparks.com/contex ) it definitely looks like I'll be needing to do that as well. It's a shame that foam was used since it is such a degradable part.
