IBM 740
The IBM 740 CRT Recorder was announced in 1954 and used with the IBM 701, IBM 704, and IBM 709 computers to draw vector graphics images, point by point, on 35 mm photographic film (i.e. microfilm). The 740 film recorder contained digital to analog converters and a 7 inch, high precision, electrostatic CRT. The raster size was 1024 by 1024, but only 256 resolved spots could be displayed on a vertical or horizontal line. Points could be displayed in one of two intensities, and a line could be drawn from a point, vertically or horizontally, to the edge of the display to form an axis.
