VRX

VRX - VRX/E

VRX is an acronym for Virtual Resource eXecutive, a proprietary operating system on the NCR Criterion series, and later the V-8000 series of mainframe computers manufactured by NCR during the 1970s and 1980s. It replaced the B3 operating system originally distributed with the Criterion. VRX was upgraded in the late 1980s and 1990s to become VRX/E for use on the NCR 9800 series of computers.
