Ought to be doable, but we're still stuck with...

   * Lower quality dot pattern - SAA5050 has a 5x9 matrix for characters,
     in a 6 dots x 10 lines space. The SAA524x has a 10x12 character
     matrix.

   * You'll want a ZIF socket for habitually reading multilingual news
     services will require lots of chip swapping. Or maybe some clever
     person to invent a buffered carrier board with a selection switch?

   * It'll still look horrid with black-as-a-colour.

Other than that, it works. ;-)


Best wishes,

Rick.
