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 Corporation during the 1970s and 1980s.

Overview

VRX replaced the B3 Operating System originally distributed with the Century series, and inherited many of the features of the B4 Operating System from the high-end of the NCR Century series of computers. VRX was upgraded in the late 1980s and 1990s to become VRX/E for use on the NCR 9800 series of computers. Edward D. Scott managed the development team of 150 software engineers who developed VRX. Tom Tang was the Director of Engineering at NCR responsible for development of the entire Criterion family of computers. This product line achieved over $1B in revenue and $300M in profits for NCR.
