Apollo/Domain

The machines were built around the Motorola 68k family of processors, except for the 'Series 10000' which had from one to four of Apollo's RISC processors, named PRISM[?].

The original operating system was Apollo's own product called Aegis, which was later renamed to Domain/OS. The Domain/OS system featured rather advanced features, for example typed I/O, network transparency, a graphical user interface and interoperability with BSD, System V and POSIX.

In 1989 Hewlett-Packard acquired Apollo, and HP's own flavor of Unix, HP-UX was available for the latter Apollo models.
