An information storage and display system for time sequential information using a cathode ray tube raster brightup display and a memory system, wherein the high speed or line scan of the raster is transverse to the time sequence of the displayed information, and the information is stored in a memory in sequence according to its order on the scan rather than its original time sequence.
A display system is described in which left to right or right to left mode may be displayed without character inversion. A read/write store is added between a display buffer and a CRT. This store stores one complete scan line of character slice bytes in sequence. The bytes may be read out either in a normal sequence or in a reversed sequence for display. As bytes are read in parallel, the orientation of individual characters is unchanged. One line of control data or selected lines may always be displayed in left to right mode, while the remainder of the display is in right to left mode.
