A data-entry station 11 (Fig. 1) can serve two operators independently with a single raster-scan cathode-ray-tube (CRT) display 12 with angled mirrors 13, 14. If the vertical sweep of CRT 12 is in the direction of arrow 15, then one operator sees the lower half 16 of the CRT field right side up but backward (i.e., from right to left), while the other operator sees the upper half 17 upside down but forward.
