This Vadem Clio is a handheld personal computer, introduced in 1998-99 as a device for mobile computing and communications. It used the Microsoft Windows CE operating system and included handwriting software and a stylus. The Clio won many design awards for its distinctive feature, a swing-arm mounted screen that can be rotated for use as a tablet or as a notebook with keyboard. This compact device and its 12-hour operation on a single charge made it suitable for use on the Space Shuttle, which had tight limits on the size, weight, and power consumption of onboard equipment. NASA reported this device as flown on Shuttle missions; the orange dot on the PDA-2 label on the case indicates that it was assigned to one of the crewmembers.NASA transferred this device to the Museum with a variety of crew equipment when the Space Shuttle program ended in 2012.
