    MARCH s looks like this http://vintagecomputer.net/univac/1219/ ...but it s a 1219-II (not B). This model was used in the mid 60 s through to the early 70 s.

      ... I have a book called Unisys Computers: An Introductory History by George Gray and Ronald Smith, circa 2008. It explains the 418 series on pages 111-112.

        I have a book called "Unisys Computers: An Introductory History" by
        George Gray and Ronald Smith, circa 2008. It explains the 418 series on
        pages 111-112.

        It says UNIVAC's St. Paul (Minnesota) location "...developed another
        real-time computer, the UNIVAC 418. The name came from its four
        microsecond memory cycle time and 18-bit word. It and the military
        version called the 1218 (also called the CP-789) evolved from the
        Control Unit Tester (CUT), which was used in the factory to test the
        peripheral equipment for larger UNIVAC systems. in 1962, Westinghouse
        Electric expressed interest in using the 418 as an industrial process
        control computer, and a modified version was used in the Westinghouse
        PRODAC 510 and 580 machines. The original version of the 418 was called
        the 418-I and had from 4,096 to 16,384 words of core memory. The first
        delivery was in June 1963, and six were produced. Much of the software
        development was done at the Washington sales office because St. Paul was
        already busy with software for the 1107 computer. Programmers developed
        the Real Time Executive (called EXEC) for the 418 which was ready in
        March 1964. It could handle the central complex (processor and memory)
        and had I/O handles for the 1004 card processor (which will be discussed
        later in this chapter), the FH-220 drum, UNISERVO IIIC tape drives, and
        communications devices. The 418-II, first delivered in November 1964,
        could have up to 65,536 words of memory whose cycle time had been
        improved to two microseconds. There were 249 418-IIs produced. Early 418
        users included NASA, the Federal Telecommunications System, the
        Department of Defense AUTODIN communications system, the New York and
        Louisiana state police, the State University of Iowa physics department,
        Illinois Bell, the Australian Overseas Telecomunications Commission,
        Multnomah County (Oregon), and the California Department of Water
        Resources. In 1967, the Fuji Bank in Japan began operation of a major
        savings account system of three 418s. A 1218 was installed at Vanderberg
        Air Force base in California in 1963 to process the radar data from
        missile launchings. It was replaced with another 1218 in 1969 which
        remained in service until 1994. Two 1218s were used for the Army's war
        room information system. That NASA Gemini space missions used fourteen
        1218s at remote sites and four 418s in switching centers. The Federal
        Aviation Agency's first Automated Radar Tracking Systems (ARTS-I) using
        a 1218 for commercil air traffic was installed in Atlanta in 1966. By
        the late 1990s, all the 418 hardware was gone, but California Water
        Resources continued to run 418 emulation on more modern UNIVAC computers
        until November 1999."

        "The UNIVAC 1219 was an improved 1218 with faster memory (a
        2-microsecond cycle time) and more input/output channels. It was the
        basis for the next version of ARTS: ARTS-1a. It used two 1219s to the
        control the New York City airports. The system was installed in 1968 and
        in full operation in 1969. (When the Federal Aviation Agency developed
        its ARTS-III system, it switched from the 18-bit architecture to the
        30-bit architecture and used a modified version of the UNIVAC 1230.
        ARTS-III was installed at Chicago's O'Hare airport in 1971 and
        subsequently at 60 other airports.) A variation called the 1219B (alias
        CP-848) was used to control launches of the Navy's Tartar, Talos, and
        Terrier ship-based missiles. The Jet Propulsion Laboratory (JPL) used a
        1219 to process photographic images of Mars from the 1969 Mariner 6
        spacecraft. By 1973 the JPL complex had grown to be two 1230s, three
        1219s, and one 1218; they were used to process images from the Mariner
        10 mission to Venus and Mercury."
