The Honeywell 6000 series computers were rebadged versions of General Electric's 600-series mainframes manufactured by Honeywell International, Inc. from 1970 to 1989. Honeywell acquired the line when it purchased GE's computer division in 1970 and continued to develop them under a variety of names for many years.
The IBM 7090 is a second-generation transistorized version of the earlier IBM 709 vacuum tube mainframe computer that was designed for "large-scale scientific and technological applications". The 7090 is the fourth member of the IBM 700/7000 series scientific computers. The first 7090 installation was in December 1959. In 1960, a typical system sold for $2.9 million or could be rented for $63,500 a month.
The AN/USQ-17 or Naval Tactical Data System (NTDS) computer referred to in Sperry Rand documents as the Univac M-460, was Seymour Cray's last design for UNIVAC. UNIVAC later released a commercial version, the UNIVAC 490 and that system was later upgraded to a multiprocessor configuration as the 494.
The AN/USQ-20, or CP-642 or Naval Tactical Data System (NTDS), was designed as a more reliable replacement for the Seymour Cray-designed AN/USQ-17 with the same instruction set. The first batch of 17 computers were delivered to the Navy starting in early 1961. A version of the AN/USQ-20 for use by the other military services and NASA was designated the UNIVAC 1206. Another version, designated the G-40, replaced the vacuum tube UNIVAC 1104 in the BOMARC Missile Program.
The UNIVAC 1100/2200 series is a series of compatible 36-bit computer systems, beginning with the UNIVAC 1107 in 1962, initially made by Sperry Rand. The series continues to be supported today by Unisys Corporation as the ClearPath Dorado Series. The solid-state 1107 model number was in the same sequence as the earlier vacuum-tube computers, but the early computers were not compatible with the solid-state successors.
The UNIVAC 1103 or ERA 1103, a successor to the UNIVAC 1101, was a computer system designed by Engineering Research Associates and built by the Remington Rand corporation in October 1953. It was the first computer for which Seymour Cray was credited with design work.
The UNIVAC 490 was a 30-bit word magnetic-core memory machine with 16K or 32K words; 4.8 microsecond cycle time made by UNIVAC. Seymour Cray designed this system before he left UNIVAC to join the early Control Data Corporation.
In computer architecture, 36-bit integers, memory addresses, or other data units are those that are 36 bits wide. Also, 36-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. 36-bit computers were popular in the early mainframe computer era from the 1950s through the early 1970s.
CMS-2 is an embedded systems programming language used by the United States Navy. It was an early attempt to develop a standardized high-level computer programming language intended to improve code portability and reusability. CMS-2 was developed primarily for the US Navy’s tactical data systems (NTDS).
In computing, a word is the natural unit of data used by a particular processor design. A word is a fixed-sized piece of data handled as a unit by the instruction set or the hardware of the processor. The number of bits in a word is an important characteristic of any specific processor design or computer architecture.
The UNIVAC III, designed as an improved transistorized replacement for the vacuum tube UNIVAC I and UNIVAC II computers, was introduced in June 1962, with Westinghouse agreeing to furnish system programing and marketing on June 1, 1962. It was designed to be compatible for all data formats. However the word size and instruction set were completely different; this presented significant difficulty as all programs had to be rewritten, so many customers switched to different vendors instead of upgrading existing UNIVACs.
The UNIVAC 418 was a transistorized, 18-bit word core memory machine made by Sperry Univac. The name came from its 4-microsecond memory cycle time and 18-bit word. The assembly language for this class of computers was TRIM III and ART418.
Naval Tactical Data System (NTDS) was a computerized information processing system developed by the United States Navy in the 1950s and first deployed in the early 1960s for use in combat ships. It took reports from multiple sensors on different ships and collated it to produce a single unified map of the battlespace. This information could then be relayed back to the ships and to the weapons operators.
The CDC 1604 was a 48-bit computer designed and manufactured by Seymour Cray and his team at the Control Data Corporation (CDC). The 1604 is known as one of the first commercially successful transistorized computers. Legend has it that the 1604 designation was chosen by adding CDC's first street address to Cray's former project, the ERA-UNIVAC 1103.
The AN/UYK-20 "Data Processing Set" was a ruggedized small computer manufactured by Univac and used by the United States Navy for small and medium-sized shipboard and shore systems built in the 1970s. It featured non-volatile magnetic core memory and was housed in a heavy-duty metal cube-shaped box which was designed to fit through a 25-inch circular hatch.
The AN/UYK-44 is the standard 16-bit minicomputer of the United States Navy. The AN/UYK-44 was developed in the early 1980s by Sperry Corporation and was completed in early 1984. The AN/UYK-44 was used in surface ships, submarines, ground C4I platforms, radar and missile control systems. The system was designed to replace the older AN/UYK-20 model.
The AN/UYK-7 was the standard 32-bit computer of the United States Navy for surface ship and submarine platforms, starting in 1970. It was used in the Navy's NTDS & Aegis combat systems and U.S. Coast Guard, and the navies of U.S. allies. It was also used by the U.S. Army. Built by UNIVAC, it used integrated circuits, had 18-bit addressing and could support multiple CPUs and I/O controllers. Its multiprocessor architecture was based upon the UNIVAC 1108. An airborne version, the UNIVAC 1832, was also produced.
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture. A realization of an ISA is called an implementation. An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost ; because the ISA serves as the interface between software and hardware. Software that has been written for an ISA can run on different implementations of the same ISA. This has enabled binary compatibility between different generations of computers to be easily achieved, and the development of computer families. Both of these developments have helped to lower the cost of computers and to increase their applicability. For these reasons, the ISA is one of the most important abstractions in computing today.
Marine Tactical Data System, commonly known as MTDS, was a mobile, ground based, aviation command and control system developed by the United States Marine Corps for the execution of anti-air warfare in support of the Fleet Marine Force (FMF). It was the Marine Corps' first semi-automated system capable of collecting, processing, computing and displaying aircraft surveillance data while also sharing that information with other participating units via tactical data link. The system was developed in the late 1950s/early 1960s when it was recognized that due to the speed, range and complexity of fighter aircraft operations effective air control and air defense demanded enhanced situational awareness.
