By the late 80s Apollo had fallen from being the #1 workstation vendor to #3 (behind DEC and Sun). There is a rumor I have run across a couple of times on the web that at one point in the mid 80s ('85 - '87) Apple was considering buying Apollo or licensing Domain/OS as the foundation for the Mac OS in order to improve stability, multitasking, etc. RELEASE HISTORY (give or takes some months either way)ĪEGIS SR2.1 - 1981 (2nd half or last quarter)ĪEGIS SR2.2 - 1981 (2nd half or last quarter) MULTICS > PRIMOS > AEGIS > Domain/OS SR10.0 With AEGIS SR9.x (SR9.7?) Apollo introduced an optional package called Domain/IX to provide POSIX compatibility, it featured the X Window System (Xapollo: possibly with ULTRIX Window Manager or Tom's Window Manager), and optional BSD or System V environments.ĭMX - Display Manager X was a Window Manager written by an HP employee that was designed to replicate the functionality of DM's pads.Īs with Unix and Unix-like operating systems Domain/OS's lineage goes back to MULTICS - with a couple more hops than UNIX: The interface provided by DM-wmgr featured editable and savable command prompts, each called a pad. Prior to this the GUI for Domain/OS and AEGIS was a window system called DM (Display Manager) with an integrated window manager named wmgr. The name AEGIS was derived from Greek mythology: Aegis was the breastplate of Zeus that was used as a shield by the sun god Apollo to revive the wounded Hector who used it to push the Achaeans back to their ships.ĭomain/OS was an acronym for: Distributed operating multi- access integrated network/Operating Systemīy default, the GUI for Domain/OS SR10.4.x and later (I believe) was the X Window System (Xdomain), Motif Window Manager, and VUE desktop environment. I always wanted to play with Domain/OS but could never find an Apollo/Domain workstation, they are apparently very rare, but I did do a lot of research - a little of which I contributed to Wikipedia, but we know how that goes.Īnyway, Domain/OS was Apollo's SR10.0.x (System/Software Release?).
