The other day I felt nostalgic and wondered over to the great archive.org site, originally to look for Commodore 64 material. Then, I thought, what the hell! and typed ‘cray’ into the search box. Lo and behold, a lot of hits! There are manuals, a CD image with some marketing or teaching material on it, but among them, two interesting CD images:
Both are UNICOS install images. I’ll have to see if they are complete and what version (and for what machine) they are, but I wanted to share the news: it appears that there is now a publicly available OS image (maybe even two) for my simulator.
