Did the 16-bit Eclipse do demand paging? If not, and the MV series did, was AOS/VS really "largely unchanged" for the latter? Next edit →
Line 5: [[PDP-11]] computers. However, it kept the simple register architecture, and the stack was kept in a special memory address ___location, as it was on the later 32 bit [[Data General Eclipse MV/8000]]. The [[Data General AOS~~/VS~~\|AOS]] [[operating system]] was quite sophisticated, and far advanced compared to the PDP-11 offerings, with [[Access control list\|access control lists]] (ACLs) for file protection. It was largely retained unchanged for the MV/8000{{fact}} which could natively run Eclipse binary code, while the [[VAX]] needed a completely new operating system compared to the PDP-11. <!-- I'm not sure if this last sentence belongs here or not; this article isn't about the MV/8000, is it? --> Production problems with the Eclipse led to a rash of lawsuits in the late 1970s, after new versions of the machine were pre-ordered by many DG customers and then never arrived. After over a year of waiting, many decided to sue the company, while others simply cancelled their orders and went elsewhere. It appeared that the Eclipse was originally intended to replace the Nova outright, also evidenced by the fact that the Nova 3 series released at the same time was phased out the next year. However, strong continuing demand resulted in the Nova 4, perhaps as a result of the continuing problems with the Eclipse.
