ABSTRACT:
Data display apparatus is described in which data from a video RAM is displayed on a CRT monitor. The apparatus includes master and slave CRT controllers which are locked together in synchronism. In operation, the displayed is divided into a main application area and a noticeboard area. The master controller is selected for display of the main application area, and the slave controller is selected for display or the noticeboard area. This allows the two areas to be displayed with different parameters, e.g. number or characters per line, without the necessity for re-programming the CRT controllers part way through the frame.
