An operating system from Fujitsu Services (formerly ICL) that was introduced in 1994 for its Series 39 mainframes and carried forth on its Trimetra systems. OpenVME is the open systems version of the VME operating system, which includes all the open interfaces previously available as an option. In late 1992, VME had already achieved XPG4 branding for its conformance to open systems standards. See VME.
