MOS Technology 8568

The VDC was designed with office suite applications in mind. Shown here is SpeedScript 128, a word processor.

The MOS Technology 8568 Video Display Controller (VDC) was the graphics processor responsible for the 80-column or RGBI display on the Commodore 128DCR personal computer. In the Commodore 128 service manual, this component was referred to as the "80 column CRT controller". The 8568 incorporated many of the features of the older 6545E monochrome CRT controller, with the addition of RGBI color.
