This is the flown processor from an on-board computer, designed and manufactured by the IBM Corporation for the Shuttle program. An operational Shuttle has five, identical on-board computers, which vote on a process to override any single and some dual malfunctions. Each computer consists of a processor like this one, plus a companion Control Unit. It is not known on which Shuttle flights this computer was used.
The NASA Johnson Space Center transferred this computer to the National Air and Space Museum, following a program in which all Space Shuttle computers were replaced by newer models.
