Actually, Domain/OS is one of Apollo's 3 operating systems... Apollo started
back when AT&T wasn't licensing UNIX for commercial use, so they had to
create their own UNIX clone, which was actually better than UNIX. This was
called Aegis, later changed to be called Domain/OS. Later, when AT&T did
start licensing UNIX, Apollo was smart enough to know that even though Aegis
or Domain/OS, depending on what you called it, was better than UNIX, the
AT&T standard was what mattered to people, so they licensed UNIX, and that
became Domain/IX, and shortly afterward, HP bought Apollo and killed
basically everything other than Prism (PA-Risc).

We have an Arium machine running Aegis Regulus. Is this a version of
Apollo's OS, or something else?

5360's can be buggers. We had one take a nose dive off a ramp. They are
heavy, awkward beasts. I would not be surprised though if it powers up
with few problems when we get around to trying it. They are built like
tanks.

Sorry but this is not very close to what actually occurred at all. I worked
at Sun (the guys that killed Apollo) from 1986 to 1995 and for part of that
time was involved with a group that picked apart Apollo in order to
facilitate its demise.
Apollo effectively invented the workstation. (yes there were others, PERQs
etc not withstanding) but for the mass market Apollo was really it. DEC did
their part with the VAXStations, and Sun did its thing with its workstations.
Aegis was Apollo's home grown, everything is an object, all written in
PASCAL, operating system. One of its chief architects, Paul Leach is over
at Microsoft now. It had a lot of features that were waayy before their
time, like memory spanning the network and disks that spanned the network
etc. Apollo made at least three really dumb decisions:
1) Invent an OS
2) Use Token Ring as their network topology
3) Staying proprietary and ignoring UNIX
Apollo had some impressive design wins, the most notable was Mentor
Graphics, however as the Sun workstations began catching on they were
unable to deal with them. Apollo also had the tendency to "implement from
spec" rather than pay any licensing. This attitude got them in trouble
because when UNIX became more dominant their response was to implement the
POSIX spec rather than license UNIX. This never worked quite right
(similarly the DEC POSIX package for VMS was never truly as useful as
"real" unix libraries) Their first go at a UNIX compatible OS was DOMAIN.
(Distributed Object Memory Accessible Integrated Network (or some such
sillynes) anyway then the bit the bullet and licensed UNIX but by then they
were where SGI is now, effectively the walking dead. HP bought them and for
a brief time was once again the leading supplier of workstations only to
lose that title again to Sun.
