160x160 pixels Can someone explain the 160x160 graphic mode in more detail If the machine normally used 23 lines of text with an 8x8 pixel matrix that would give 23 8 184 pixels of height Double height characters would imply half of that i e 92 pixels The 200 characters mentioned is enough for a square shaped array of 14x14 characters 14 8 112 Since 92 112 160 I am confused
