Beautiful pictures of a space shuttle HP-41CV (pictures courtesy of Ladd Observatory and Brown University).

The date code is 2303S, meaning it was manufactured back in 1983 (probably in Singapore). It was donated to Brown University with no batteries or software installed. As you can see though, it’s fully functional. SMS means “Shuttle Mission Simulator”.
