As a side note, I have heard that the first Cray-1 (the one without error
correction) is still running somewhere (in England, I believe), and that 
its MTBF is now much more than 4 hours, as the memory chips most likely to
cause errors have been found and replaced over the years.  As a result, it
is not only very reliable but also runs faster than other Cray-1 machines
*because* it has no error correction!
