Ferranti MRT
The Ferranti Market Research Terminal (MRT) was, arguably, the world’s first application-specific handheld computer.〔Patent "''Data Recording Technique and Apparatus (Market Research Terminal)''" – GB19820022834, WO1983GB00195〕〔(1986) “''The Market Research Terminal & Developments in Survey Research''”, European Journal of Marketing, Vol. 20 Issue: 2, pp.35 - 39.〕 It was designed specifically for the market research sector as a means to augment the regular clipboard schemes that, at the time, were common-place, in social and market research.〔“''The Digital Home: a New Locus of Social Science Research''“. In The Handbook of Emergent Technologies in Social Research, Oxford University Press, 2010〕 The Ferranti Market Research Terminal (MRT) is also of historical significance to the computing industry since it marked the last original computer design from Ferranti, a long established business (started 1882) that had risen to fame through a collaboration Manchester University to produce the "Mark 1", the world’s first commercial computer and later with Cambridge University producing the "Atlas" and "Titan" computers which, at their peak, held around 25% of the computing market.
== History ==
Ferranti Plc produced two versions that were labelled the MRT-100 and MRT-200 and based on an original 1978 prototype called the ''Questronic'' which had been designed at Sheffield University as part of a collaboration between the Department of Electronics and Electrical Engineering and the Department of Geography.〔(Questronic website )〕 While it is difficult to imagine the context of this product development in the late seventies, it is useful to remember that the IBM PC (which has brought the Windows desktops and laptops that are now commonplace!) was only introduced on the 12th August 1981. If one ignores calculators, then handheld computers appeared in July 1980 with, perhaps, the first being the Tandy Pocket Computer (Radio Shack TRS-80 Pocket Computer). Later in the same year, Matsushita (now the Panasonic Corporation) produced a handheld computer marketed under the Panasonic and Quasar brand. However, these devices were, of course, general purpose handheld computers unlike the application-specific MRT introduced by Ferranti. A merger in 1989 with the American “International Signal & Control Group” (ISC), led to Ferranti going into bankruptcy in December 1994. With that came the end of the Ferranti MRT and, effectively, Ferranti with its long lineage of UK innovative computing and electronics research, development and manufacture.
