      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."
