1947Williams & Ritson in Jrnl. Inst. Electr. Engineers XCIV. iia. 112 The paper presents an outline of a method which will allow automatic control systems to be studied experimentally by means of an electronic apparatus called a ‘simulator’, which is constructed so as to have the same characteristic equation as the control system. 1950, etc. [see flight simulator s.v. flight n.1 15]. 1958Engineering 21 Mar. 374/1 A colour print simulator will be demonstrated... The basis of the new equipment is a closed-circuit colour-television system, whose characteristics can be adjusted to match those of a desired printing system. 1967Guardian 6 Mar. 12/2 The world's first locomotive simulator for driver training at the Willesden electric depot. 1970Daily Tel. 16 Feb. 3/3 For the make-believe flight, Prince Philip and Young had climbed into a lunar-landing craft simulator. 1972Sci.

Ibid., A simulator is useful when changing from one computer to another. 1977Sci. Amer. Sept. 153/1 Thus users of large computer systems and time-sharing services have access to cross-software assemblers, compilers and simulators (programs that enable a computer of one make or model to duplicate the actions of another). 1978J. C. Cluley Programming for Mini⁓computers ix. 216 In order to help tracing errors, the simulator program has many of the features of a minicomputer debugging program. |
