TextBuffer
The color byte is seperated into two nibbles. The first nibble is the background, the second is the foreground. For example, if the word at B000:0000 is 7054h (using the little endian notation), this would mean 54h = 'T', 7h = light grey, and 0h = black. The letter T would be displayed in the top left corner, light grey text on a black background.
