Most often the VDC chip is completely integrated in the logic of the main computer system, its video RAM appears in the memory map of the main CPUcotroller sometimes controloer functions as a coprocessor that can manipulate the video RAM contents independently.

Input signal from the CRT system signifying that a light pen signal has been detected. This said, it is not completely clear when a “video chip” is a “video display controller” and when it is a “video display processor”. The SBC can be used for full or half-duplex operation and the operating mode of each of the four channels, the data format and other functions are all individually programmable. These are used alternately to load data from main memory and refresh crr display.
