IBM 1720

Last updated

The IBM 1720 was a pilot project to create a real-time process control computer based on the IBM 1620 Model I.

In computer science, real-time computing (RTC), or reactive computing describes hardware and software systems subject to a "real-time constraint", for example from event to system response. Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines". The correctness of these types of systems depends on their temporal aspects as well as their functional aspects. Real-time responses are often understood to be in the order of milliseconds, and sometimes microseconds. A system not specified as operating in real time cannot usually guarantee a response within any timeframe, although typical or expected response times may be given.

Automatic process control in continuous production processes is a combination of control engineering and chemical engineering disciplines that uses industrial control systems to achieve a production level of consistency, economy and safety which could not be achieved purely by human manual control. It is implemented widely in industries such as oil refining, pulp and paper manufacturing, chemical processing and power generating plants.

Only three 1720 systems were ever built: one for the Amoco oil refinery in Whiting, Indiana; one for the Socal oil refinery in El Segundo, California; and one for E. I. du Pont in Wilmington, Delaware. All were installed in 1961. The Amoco and Socal systems ran for many years.

Amoco former global chemical and oil company

Amoco Corporation, originally Standard Oil Company (Indiana), is a global chemical and oil company that was founded in 1889 around a refinery located in Whiting, Indiana, United States.

Oil refinery industrial process plant where crude oil is processed and refined into more useful products

Oil refinery or petroleum refinery is an industrial process plant where crude oil is transformed and refined into more useful products such as petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel and fuel oils. Petrochemicals feed stock like ethylene and propylene can also be produced directly by cracking crude oil without the need of using refined products of crude oil such as naphtha.

Whiting, Indiana City in Indiana, United States

Whiting is a city located in the Chicago Metropolitan Area in Lake County, Indiana, which was founded in 1889. The city is located on the southern shore of Lake Michigan. It is roughly 16 miles from the Chicago Loop and two miles from Chicago's South Side. Whiting is home to Whiting Refinery, the largest oil refinery in the Midwest. The population was 4,997 at the 2010 census.

The 1720 led to the IBM 1710 Process Control systems that IBM introduced in March 1961; these were cheaper and less elaborate than the 1720.

The IBM 1710 was a process control system that IBM introduced in March 1961. It used either a 1620 I or a 1620 II Computer and specialized I/O devices.

The IBM 1620 was announced by IBM on October 21, 1959, and marketed as an inexpensive "scientific computer". After a total production of about two thousand machines, it was withdrawn on November 19, 1970. Modified versions of the 1620 were used as the CPU of the IBM 1710 and IBM 1720 Industrial Process Control Systems

The IBM 7030, also known as Stretch, was IBM's first transistorized supercomputer. It was the fastest computer in the world from 1961 until the first CDC 6600 became operational in 1964.

A distributed control system (DCS) is a computerised control system for a process or plant usually with a large number of control loops, in which autonomous controllers are distributed throughout the system, but there is central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers located at a central control room or within a central computer. The DCS concept increases reliability and reduces installation costs by localising control functions near the process plant, with remote monitoring and supervision.

The IBM 1800 Data Acquisition and Control System (DACS) was a process control variant of the IBM 1130 with two extra instructions, extra I/O capabilities, 'selector channel like' cycle-stealing capability and three hardware index registers.

The IBM 1711 Data Converter was part of the IBM 1710 process control computer. The 1711 contained an analog-to-digital converter that accepted signals from the IBM 1712 Multiplexer and Terminal Unit that were between -50 millivolts and +50 millivolts and converted them into signed, four decimal digit numbers that were stored in the 1710s core memory.

The IBM 305 RAMAC was the first commercial computer that used a moving-head hard disk drive for secondary storage. The system was publicly announced on September 14, 1956, with test units already installed at the U.S. Navy and at private corporations. RAMAC stood for "Random Access Method of Accounting and Control", as its design was motivated by the need for real-time accounting in business.

Texas City Refinery explosion

The Texas City Refinery explosion occurred on March 23, 2005, when a hydrocarbon vapor cloud was ignited and violently exploded at the ISOM isomerization process unit at BP's Texas City refinery in Texas City, Texas, killing 15 workers, injuring more than 180 others and severely damaging the refinery. The Texas City Refinery was the second-largest oil refinery in the state, and the third-largest in the United States with an input capacity of 437,000 barrels (69,500 m3) per day as of January 1, 2000. BP acquired the Texas county refinery as part of its merger with Amoco in 1999.

MODCOMP was a small minicomputer vendor that specialized in real-time applications. They were founded in 1970 in Fort Lauderdale, Florida. In the 1970s and 1980s, they produced a line of 16 and 32-bit mini-computers. Through the 1980s, MODCOMP lost market share as more powerful micro-computers became popular, and Digital Equipment Corporation's VAX and Alpha systems continued to grow. The company successfully survives today as a systems integrator.

Canada's natural gas liquids industry dates back to the discovery of wet natural gas at Turner Valley, Alberta in 1914. The gas was less important than the natural gasoline - "skunk gas" it was called, because of its distinctive odour - that early producers extracted from it. That natural gas liquid (NGL) could be poured directly into an automobile's fuel tank.

The history of operating systems running on IBM mainframes is a notable chapter of history of mainframe operating systems, because of IBM's long-standing position as the world's largest hardware supplier of mainframe computers.
