Yeah, I should probably add screenshots of earlier versions of those (or in the case of Domain/OS, screenshots of dm).
Rather than just another name for Domain/OS, Domain/IX was actually a Unix compatibility layer that was an add-on product for pre-SR10 AEGIS versions, with SR10 merging it into the base OS (pre-SR10 had no built-in Unix compatibility).
AFAIK even though it's usually associated more with HP-UX, VUE actually originated at Apollo before HP bought them, although I'm not sure if they ever actually released it before the acquisition.
