GEORGE was the name given to a series of operating systems released by International Computers and Tabulators (ICT) in the s, for the ICT series of computers. These included GEORGE 1, GEORGE 2, GEORGE 3, and GEORGE Initially the series machines, like the Ferranti-Packard on which they were based, ran a simple operating system known as executive which allowed the system Developer: International Computers and Tabulators.

ICT was the name given to a series of mainframe computers released by International Computers and Tabulators (ICT) and later International Computers Limited (ICL) during the s and '70s.

The series was notable for being one of the few non-American competitors to the IBM System/, enjoying significant success in the European and British Commonwealth : bit.

GEORGE 3, the operating system, unified control of batch and interactive (“MOP”—Multiple Online Programming) usage with a single command language.

When ICL was formed in as a result of the merger of International Computers and Tabulators (ICT) with English Electric Leo Marconi, the company considered a number of options for its future product line.

These included enhancements to either ICT's Series or the English Electric System 4, and a development based on J. Illiffe's Basic Language Machine. A set of teams was set up to formulate a set of proposals, for example basing it on an existing or proposed system, with main candidates the existing ICL series and EELM System/4 series, the Basic Language Machine, an elegant, fundamental re-think of computer architecture developed by a team in ICL's labs under the direction of John Iliffe.

The was based on discrete transistors*, while the A series had graduated to integrated circuits.

Description ICL 1900 series: Operating systems GEORGE 3 and 4. PDF

The newer computers now had something much more like a modern operating system. GEORGE 1 and 2 were fairly simple batch OS, but GEORGE 3 was quite a sophisticated multi-tasking OS that even included some interactive terminal access.

Origins. When ICL was formed in as a result of the merger of International Computers and Tabulators (ICT) with English Electric Leo Marconi and Elliott Automation, the company considered a number of options for its future product line.

These included enhancements to either ICT's Series or the English Electric System 4, and a development based on J. Iliffe's Basic Language Machine. International Computers Limited (ICL) was a British computer hardware, computer software and computer services company that operated from until It was formed through a merger of International Computers and Tabulators (ICT), English Electric Leo Marconi (EELM) and Elliott Automation in The company's most successful product line was the ICL Series range of.

Publisher Summary. This chapter focuses on the use of systems for archival description, retrieval, and management. There are three types of system: (1) systems for producing series lists or descriptions for purposes of administrative control and general archival control, including publication; (2) systems for information retrieval, that is, for the intellectual control of archive accumulations.

It uses an ICL S computer GEORGE 4 operating system, an elaborate infrastructure of access peripherals, and three simple COBOL programs. Automated systems for records management are in operation in several other countries.

Running the program under the ICL GEORGE 3 operating system SMRE is linked by teleprinter console to an ICL Series computer based at Norwich.

The system is operated under ICL's GEORGE 3 system (ICL, ), which enables the console user to input information, run programs, and obtain results by means of macro commands.

A series of smaller machines (,and later A, A and A), with their own Executives (e.g. E3RM) and George1 and George 2 operating systems, were developed by the ICL Stevenage site. Nope - George 3 was the operating system on the ICL series of computers - analogous to what Unix, Linux, Windows server etc were to later systems albeit less sophisticated.

"The Algol R system is available in two versions, one which runs under GEORGE 3 (or GEORGE 4), and one which runs under Operators Executive (or any other operating system)." Susan Bond. An oral history conducted in by Janet. More on the ICL Series submitted by Bob Eager I worked (and still do) at the University of Kent.

We had an early from For the early part of that time I was a part time programmer, part-time postgrad; I was charged with a lot of bug reporting. The was the fastest System model and used a 32k high speed buffer to, in effect, reduce the main storage cycle time from nanoseconds to 54 resulting in faster overall processing times.

With an integrated floating-point processor and ability to process up to seven operations simultaneously, the s were used for highly intense. This is a summary of known implementations of ML/I, organised by operating system.

There is also a summary organised by hardware platform. The summary contains links to individual pages describing the particular implementations. EVOLUTION OF SOFTWARE Evolution of Operating Systems Operating System (OS) is the most essential software for a computer for it is the master control program that runs the computer.

In s, when computers were developed mainly for research and scientific activities, the early operating system was developed at Bell Labs innamely.

- Span of the Range (By Virgilio Pasquali –November ). The brilliant simplicity of the original FP design and the design skills of the ICT engineers made it relatively easy to expand the design into a series of systems spanning a wide range of performance and price.

Unsurprisingly, the greater difficulty was encountered in expanding the range upwards. ICL therefore had decided to concentrate on the new series and abandon the A.

Efforts would be made to make transfer of programs from both System 4 and easy. ICL A. The Committee decided to continue with the purchase of the A with the aim of using that as the front-end to the new ICL top-end machine, called initially P MINIMOP was an operating system which ran on the International Computers Limited (ICL) series of computers.

MINIMOP provided an on-line, time-sharing environment (Multiple Online Programming, or MOP in ICL terminology), and typically ran alongside George 2 running batch jobs.

MINIMOP was named to reflect its role as an alternative to the MOP facilities of George 3, which. Concise Microsoft O.S.
