ICL VME
VME (Virtual Machine Environment) is a mainframe computer operating system developed by the UK company International Computers Limited (ICL, now part of the Fujitsu group). Originally developed in the 1970s (as VME/B, later VME 2900) to drive the then new ICL 2900 Series mainframes, it is now named OpenVME, incorporates a Unix subsystem, and runs on ICL Series 39 and Trimetra mainframe computers, and industry-standard x86-64 servers.
