ABSTRACT:
A computer graphics system. The system includes a video memory having a shift register adapted for split shift register transfers, and digital computer for controlling the video memory and having a tap point counter clocked by a shift clock signal and also having a blanking circuit with a blanking output. Further, logic circuitry enabled by the blanking output is connected to initiate an extra shift clock pulse for the tap point counter during a blanking interval. Other systems, palette devices, and methods are also disclosed.
