  2. The way the display card handles
  3. graphics is to assign each dot
  4. location two numbers, one for its
  5. horizontal position and one for
  6. its vertical position.  To put a
  7. dot in the upper left corner of
  8. this screen, the card would tell
  9. the monitor to put a dot at 0,0.
  10. And the lower right of this screen
  11. is 639,199. The middle is 320,100.

  94.    To draw a line, the card would
  95. tell the monitor to put dots at a
  96. series of locations. There are
  97. some more RAM chips on the
  98. display card to remember which
  99. places dots are to be located.
  100. The text character patterns of
  101. dots are stored in ROM chips on
  102. the display card.
