I'm not sure where one might normally expect to discuss research operating systems from the 1980s and 90s, but since it ran on Sun-2 through Sun-4 and DECstations, I'll start here.
I have the Sprite disk image for the DECstation 5000/200 running under GXemul (see https://github.com/OSPreservProject/sprite), but this is a minimal ~80MB image. I'm wondering if anybody has already gone through the exercise of figuring out how to create a new disk image large enough to, for example, load the source tree and see how far it is from compiling. My calendar is full until mid-December, so I won't be taking a swing at this in the next few weeks. But I had a moment and thought I'd start asking if anybody's been down this road in the past decade or two. Thanks, --S.
