Speaking of museums, if you are ever in Bonn Germany or nearby (it's a
20 minute train trip from Cologne) don't miss the Arithmeum, a
remarkable collection of mechanical calculators. They let you
play with a lot of them.
There's also a little more modern computer stuff but the emphasis is
on mechanical, both digitial calculators and analog such as the many
kinds of slide rules and dividers.

The ABC was dismantled, lost, and later rebuilt. It is currently housed at the Durham Center of Iowa State University in Ames, Iowa. The ABC was
later credited as the first digital computer with all the components of a computer around that time. It was built before ENIAC and before WW 1.

nitpick: before WWII, not WW 1

Dr. Stewart disassembled it when he was clearing space in
the basement of the physics building for an office when he
was a grad student (Dr. Stewart was CS department chairmen when I was
there). The only remaining piece was the memory drum.
I had the memory drum in my office on-campus for a
couple of months before VIESHA when I was com sci club
president.

The restoration was complete. It was at the computer history
museum last time I visited - I'm not sure where it is today.
I also took Dr. Atanasoff to dinner after he gave a presentation
to the CSC in 1981, IIRC.
