Anxious to see how this turns out. Very interesting!

#22Now if only someone can get this guy some Cray-I software. Even the Computer Museum, which has an actual Cray-I they use as a piece of furniture, apparently doesn't have any. The Cray-I is a rather simple machine at the logic level. There are 64 of some registers, but they're all the same. The instruction set is small.
To be fair, booting the Cray would require a good sized power substation. The power bill would be... impressive.
The 1s used between 100kW and 150kW. So a small substation. The XMP used 200-300kW. The 2 used 150-200kW.
There was a YMP model (the EL) that could be power off normal mains (220v).
Energy efficient was different back then.

#23This is so awesome. But what I'd really like is that to-scale case and put a small PC in it. Even if one does not care at all about its historic significance, the Cray-1 was one of the most visually appealing computers I have ever seen. Having a miniature version of it sitting on my desk would be extremely cool.
Well, just saying: http://www.thingiverse.com/thing:26671 On a slightly larger scale, I will, eventually, in my infinite space time, have a full size wooden cray I in my rec room as a sitting couch. I have the carpentry skill and tools and structural experience to pull this off. For many years I have periodically worked on dimensioned drawings. My strategy revolves around making eleven identical 22.5 degree segments…
Nice! Thanks for the link!
