Apollo/Domain

Apollo / Domain is called the workstation series manufacturer Apollo Computer Inc. were produced 1980-1989. Although the names are now scarcely known was Apollo 1980-1987 as the largest and most important manufacturer of networked workstations. Most workstations used a Motorola 68k CPU with its own Apollo chipset. However, a major exception is the DN10000 workstation, used it as a processor developed in-house, one of the first RISC processors, the Apollo PRISM processor, which is said to have stood as godfather to the PA - RISC CPUs from Hewlett -Packard.

Operating system

The original operating system, developed in-house, called Apollo Aegis, Aegis was later renamed Apollo Domain / OS. Aegis was an elegant stand-alone operating system. End of the eighties it was extended POSIX compliant. It is noteworthy that large parts of the operating system were not as usually written in C, but in an in-house version of Pascal. Among the most successful and elegant features included the network implementation. You could practically everything that was possible locally, on the network outsource and distribute. A functionality that is unique in this transparency for its time. Legendary is also the successful and time-saving system administration.

Compatibility

The workstations had its own hardware and CPUs that did not come from Intel. Therefore, for obtaining the PC compatibility additions were necessary. There was comparatively slow software emulators (see virtualization ), but also fast hardware -based add-in cards with I286 or i386 CPU.
