Abstract: Apparatus for rotating a cathode ray tube (CRT) which is operated as a graphic display through 90 degrees such that different size pages of data may be displayed while minimizing the control circuitry required. The display deflection yoke is fixedly attached to a support frame for the display. The CRT is rotatably mounted within the yoke and held by annular thrust bearing which allows the CRT to be rotated 90 degrees. A switch is actuated by the rotation of the CRT to select between sets of control resistors to control the raster scan of the CRT in accordance with its orientation.
