© Science Museum / Science & Society Picture Library
This touch sensitive machine was first introduced in 1983 and uses ideograms instead of Roman numerals. There are 1,533 ideogram 'keys' plus others which control certain functions giving a total of more than 3,500 posible characters which can be printed on to paper. Like English language typewriters a number of ideograms that had been 'keyed' into the machine appeared in a viewing window before being printed, this allowed for corrections to be made.
