GRAPHICS OVERVIEW

All of the graphics abilities of the Commodore 64 come from the 6567

Video Interface Chip (also known as the VIC-II chip). This chip gives a

variety of graphics modes, including a 40 column by 25 line text display,

a 320 by 200 dot high resolution display, and SPRITES, small movable

objects which make writing games simple. And if this weren't enough,

many of the graphics modes can be mixed on the same screen. It is

possible, for example, to define the top half of the screen to be in high

resolution mode, while the bottom half is in text mode. And SPRITESwill

combine with anything! More on sprites later. First the other graphics

modes.
