So if I understand it correctly, your intention is to make an entirely new UNIX system from scratch, inspired by, or as close as possible to IRIX. Correct? Is the plan to make this for SGI hardware or modern PCs?

Writing an operating system, or even just a kernel (are you writing the whole system or just a kernel?) is certainly a fun project. I like it, and I have done similar projects a few times. But even taking it to the point where it's functional and advanced enough for any similarities or differences to any specific UNIX system like IRIX to come through, will take an enormous amount of effort. Like years. Isn't it a bit pre-mature to call this anything other than "a new homebrew UNIX-like OS project"?
