https://www.zdnet.com/article/sgi-denies-links-with-alleged-bitcoin-founder-craig-wright/From 2015:
High performance computing firm SGI has denied any involvement with Cloudcroft Supercomputers Australia, a supercomputer firm that was founded by suspected bitcoin founder Craig Wright under his parent company DeMorgan.
In a letter featuring the SGI letterhead and the supposed signature of SGI APAC service director Greg McKeon, SGI acknowledged it would be assisting Cloudcroft Supercomputers Australia in the development of hyper-density machines and supercomputers.
The letter for some reason has been REMOVED from wayback.

To whom it may concern,
SGI, the trusted leader in high performance computing, is pleased to work with Cloudcroft Supercomputers Australia in assisting the development of their hyper-density machines and supercomputers. As a global leader in high performance solutions for computers, data analytics and data management, SGI considers Cloudcroft a worthy partner in the goal to accelerate time to discovery, innovation and profitability.
Cloudcrofts proficiency in information technology is highly respected by SGI, particularly in the domains of cryptography and computer security. Cloudcroft brings this expertise to the design of its sophisticated supercomputer-based applications.
SGI and Cloudcroft have worked together with SGIs flagship ICE platform for powerful distributed=memory supercomputers to build Sukuriputo Okane, Cloudcrofts first supercomputer currently ranked #327 in the world. You can find more information about SGIs ICE supercomputing platform here:
https://www.sgi.com/products/servers/ice/This super computer was tuned to 939.67 TFlops which would see it pushed into the Top 100 systems in the Top 500 HPC realm. This could have only been achieved through commitment to cooperation. SGI is very pleased with this alliance in pushing the boundaries of distributed-memory systems.
Next we must perfect the integration of Nvidia Tesla and Intel Xeon Phi accelerator cards to reach new heights in supercomputing excellence in Australia. SGI offers both accelerator options for its products thus working with Cloudcroft to ensure the next supercomputer stays green, reaches the highest ranks of the T500 list, and continues to perform through innovation is very synergistic. We look forward to a long, sustained relationship with this highly-focused Australian firm.
Yours sincerely,
Greg McKeon - Director

Particularly curious is the lack of ® symbol in comparison from other form letters from that era.
It could have an innocent explanation.
