The touch terminal

The 'Touch Terminal' is a microprocessor-based intelligent terminal specially geared to the control of complex processes. It would be ideally suited to the control of a high-energy physics experiment. It incorporates three of the features which have made the SPS control system a successful and widely acclaimed means of accelerator control. These are a 'touch panel' with computer writable legends, a full graphics display screen, and a high level interpretive programming language. It can be used in two modes. First, as a peripheral to any host computer, so providing the host with touch panel and display facilities at minimum overhead. Secondly, it can be used as a stand- alone system with its own high level NODAL language. The terminal is compact and uses an internal 11 slot CAMAC bus. This enables the power of the terminal to be increased by adding appropriate CAMAC modules. A CAMAC controller using a powerful microprocessor provides the intelligence for the terminal operation.
