  Internal Atari ST Trackdisplay (C) 1991 Beeblebrox Industries Unlimited.
  ========================================================================
  
  Brief description on how to install the trackdisplay unit.
  
  Connect TR00 to pin 23 of WD1772, WP to pin 25 of WD1772, WG to
  pin 6 of 7406 IC next to the WD1772 (U14), in order to avoid having
  to invert the WG signal that origins from pin 21 of WD1772.
  STEP to pin 2 of 7406 (U14). (Originates from pin 16 of WD1772!!!).
  Connect DIR to pin 17 of WD1772, SS to pin 21 of YM2149, +5V to pin 15
  of WD1772, GND to pin 14 of WD1772. That's all folks! If you've followed
  my directions, this gadget will now work fine - at least it did for me...
