A method has been proposed to provide multipath user feedback at graphics workstations used in semiconductor processing operations. The proposal suggests the incorporation of two audio stereophonic paths or four quadraphonic paths into the workstation. At the dual-headed graphics workstation 1 (Fig. 1) an audio device is required for the alphanumeric display 2 and the graphics display 8. The audio feedback is typically programmed to alert the operator of events, such as initial program load (IPL) sequence, as well as to provide positive feedback, negative feedback and emergency feedback signals. The audio paths proposed to provide this feedback would be activated singularly and/or in parallel. The audio path outputs to be incorporated in the workstation are at the upper left 3, upper right 4, lower left 5 and lower right 6.
