Does anyone know where to get actual Cray PVP code?

Question

I want to write a emulator for one of the older Crays, but I've run into a stumbling block. I can't seem to find any actual code for them. (Which kind of makes sense I suppose, most of them would have been used for defense and the like..) Does anyone know where I might find something? Binaries or source, it's all good. The thing I'd like the most is a binary of COS. Thanks in advance.

The CAL manual is online :
