Phenolic Resin 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.
