That is, 4 of the computers are. The 5th was designed and built by Rockwell (Rockwell doesn't trust IBM computers either). I do not know how different the Rockwell machine is to the IBMs, but it is the only computer that has never failed (it did cause the sync problems on the very first attempted launch, but only because the 4 IBMs ganged up on it...).
