Abstract: A display work station has a rotatable CRT display 18 for presenting data in a vertical and horizontal orientation. The orientation of the CRT display 18 causes activation of the swiiches that control the electronic logic to modify the addressing sequence of data retrieved from a refresh memory so that the data are presented properly on the CRT face.
