/*      Oak Techologies OTI-067/077/087 mode definitions

 *      12 September 1994 Christopher M. Wiles ([e-mail])
 *      The below mode definitions work just fine on my '87 board.  As I
 *      do not have either a '67 or a '77 to play with, I cannot guarantee
 *      that any or all of these modes will work with cards based on those
 *      chips.  Therefore, use at your own risk (and let me know if they work).
 *
 *      NB: If any of these modes are displaced horizontally, change the fifth
 *      byte (in units of 8) of the CRTC section in the definition in 
 *      question.  Increment the value to move the screen left, decrement to
 *      move the screen right.
