I live in the metropolitan DC area and recently visited the Smithsonian National Air and Space Museum. It has an exhibit entitled 'Beyond The Limits' which depicts the role of computers in the development of aviation and space flight. An HP 35 (version 2) hangs near the entrance to the exhibit. Further in the exhibit, there is a display of an HP 41CV used aboard several Space Shuttle missions. The following links are pictures of this exhibit:

Apparently the usual 41 case has been replaced by something more NASA'ish. It's also interesting that the 41 has a translucent keyboard overlay (which in retrospect seems like a great idea) and color coded sticky labels. Also, there is a picture (which hangs below the 41) of astronaut Sally Ride taken aboard the Space Shuttle Challenger with a 41 next to her.
Just curious if anyone has come across information about the programs the astronauts used on the 41's? Also, I'm wondering if there are any other 'physical' museums that display Hewlett Packard calculators?
