You have to keep those sort of museums up to date. As I recall the Computer History Museum in Boston, they had some interesting historical artifacts like Sage I think. But a fair bit of the museum was devoted to supposedly state of the art computing, some interactive. As a lot of the local computer companies went away, a lot of the the exhibits started looking pretty dated--and I'm sure a lot of funding dried up as well.

The Museum of Play and Wegmans are really class acts.

My kids just use the actual self checkout machines / lanes.
