Ask HN: Do you know about Cray OS?

(http://chrisfenton.com/cos-recovery/)

This guy has built a replica Cray-1a. He wants to run original (real) software, but is having trouble getting his machine to boot.

This is the kind of challenge that some people on HN should be able to help with.

(I have no connection to him. I saw this on hack-a-day. I think the replica is awesome. And I really like people who keep obsolete software running.)
