STAGE III - Figure 3 Stage III repr-esents the use of more than one remote control system with the addition of a data storage and retrieval device that stores the static or variable control signals which were manually actuated in Stage I. STAGE IV - Figure 4 Stage I V is the same as Stage III. There is the addition of what we call a Synthesized Master Control Console containing all of the controls for each associated system. STAGE V - Figure 5 Stage V is the same as Stage I V. Another element has been incorporated into the Synthesized Console. It is a vi su aI display of the operational feedback of the associated systems. There are in tOday's theatres basic production and design limitations that will be alleviated by further utilization of the available technical and engineering skills. These problems are basically defined as follows: the need for accuracy, speed, reliabi lity and overall production co-ordination. The limitations they represent are compounded by overall factors such as lack of time, money and effective technical assistance. Given a moment of brief recollection, can anyone of us recall a production situation where we did not experience some or all of these handicaps?
