MOS Technology 8563

The 8563 Video Display Controller (VDC) was an integrated circuit produced by MOS Technology. It was used in the Commodore 128 (C128) computer to generate an 80-column (640 × 200 pixel) RGB video display, running alongside a VIC-II which supported Commodore 64-compatible graphics. The DCR models (as well as a few D-models) of the C128 used the later and more technically advanced 8568 [D]VDC controller.
