Abstract
A screen display unit includes a display RAM to which a CPU writes palette codes corresponding to character codes, and a selector for selecting display color data read from one of two color palettes on a character code by character code basis in response to the palette codes read from the display RAM. The selector can select one of the two color palettes on a character code by character code basis, thereby making it possible to carry out display in a greater number colors on the same screen than the number of colors indicatable by the display color codes stored in the display RAM without increasing the capacity of a font data memory.
