Two move controllers are provided for a refresh matrix buffer of a CRT display, the first to effect columnar movement and the second to effect row movement, the use of the controllers thereby effecting a scroll right/left or a scroll up/down motion. The move controller is also utilized to move characters from a special font table to the buffer, thereby freeing the host processor from this chore.
