Very interesting story.

I used to regularly visit SGI documentation due to OpenGL/IrisGL, Inventor, and the original HP STL C++ documentation that SGI hosted, and naturally dive into Irix documentation in boring days.

That was a pretty epic story. I'll admit that I skimmed a few parts. :)

Sad that it's discontinued, but mostly it's remarkable that so much was done by so few people.

I wish it was still supported, but I'm sure I was one of very few that was actually using it! Even then it was just for fun.
As I understand it, Loongson is very close to MIPS. I think I remember reading that just 4 patented instructions were removed from the MIPS ISA, and I am not even sure that they were replaced.

If so, that means that new MIPS-family hardware is being made today. And ISTM that represents a new target market or audience for this.
