Consider that the Shuttle is a late 1970s early 1980s design.    I have 
never heard anything dependable about the shuttle using OS-9, but it 
did (whether it still does or not is another question) use three 
redundant 6809 based systems for its flight computer.  The B-1's 
systems were designed around IIRC eight 6809 based computers.
