	~~The '''VDG''' or '''MC6847''' is the video display generator from Motorola used in the [[TRS-80 Color Computer]]~~

	~~It can display text and graphics within a matrix of 256 pixels wide by 192 lines high.~~

	~~It can display a maximum of 9 colors: black, green, yellow, blue, red, buff (almost-but-not-quite white), cyan, magenta, and orange.~~

	~~It is also used in the following computers of the time: [[MC-10]], [[Dragon]], [[Laser 200]] and [[Acorn Atom]].~~
