Looks like MTS has been much better preserved than Cray OS.

Yes, indeed.  In the process we've preserved more than just MTS.  We've been able to give source back to the people who wrote it a couple of times because it was in the MTS distributions even though they lost it themselves.

I was in the Science Museum in London recently and had a chance to sit on a Cray 1.  They have only (or mostly) just the CPU, but it looks fairly complete.  It's still an impressive machine even if it is slow by modern standards.
