Abstract
An inexpensive colour-picture generating system is described and a few applications are indicated. The basic equipment comprises a microprocessor; a colour television monitor with R, G, and B inputs; and a number of video memories. The most important characteristic of the apparatus is the way in which video memories are used in combination with a set of colour registers and very fast digital/analog converters. The equipment permits display of any kind of figure with a maximum of eight colours simultaneously present. Figures may be generated point by point by the experimenter, or by computer. Colours can be changed continuously with the R, G, and B channels each receiving one out of 256 possible values.
