Detailed Description

Vdc module.

This file contains labels that map to the VDC registers of the Commodore 128.; Labels are intended to be used in assembly for 6502 with KickAssembler.

The Commodore 128 has a VDC chip, which is responsible for controlling the video display. The VDC chip controls the screen resolution, color, character set, and other display parameters.
