CyberVision64/3D No or instable operation with Zorro II/III tower conversions Type of Failure: The CyberVision64/3D refuses to work on Your Zorro-II/III Tower expansion properly or does not work at all. Cause: The CyberVision64/3D was designed for original Amiga boards with Zorro II or Zorro III. Since some of the Zorro II/III expansion boards for the tower expansion sometimes behave a bit different (for example, different timing or a bad quality of the signals) than the original Amiga board with Zorro II/III slots, the above mentioned failiures may occur. Solution: Please contact the manufactuer of Your Tower expansion.
