Babbage’s Difference Engine No. 2

We made another stop on the “Scientific Traveler Tour” this afternoon at the Computer History Museum in Mountain View, CA.  Charles Babbage’s Difference Engine No. 2 was demonstrated for us four relics from before the personal computer age.

There were a few other relics in the museum…

10Jun (20) A Gold Star for the first daughter or son-in-law to guess what is hanging from this man’s belt!

  1. Being a geek, my first guess would be a slide ruler. Another possibility would be a mechanical part (key) used to operate the first computer. Yikes! Good question! Hope your daughters figured it out before the son-in-laws.

    You'll have to let me know the answer when you come back to Jamestown. Have a good one!

  2. I agree -- a slide ruler! If I'm right I'll share the prize with Susan! -Jen
