(5) The character generator matrix ROM stores all the character shapes in a
matrix-format. The character data buffer tells the character generator which matrix
block to select for the next required character. The generator ROM also has an
input from the Y-dot counter which selects a horizontal slice of the selected block.
The output of the generator ROM is, therefore, a dot pattern representing one slice
of the character.
