he Mediator ZIV works like any other Mediator (more like the Mediator SX than 1200 though) so the supported list of cards on ELBOX's homepage should be valid.
The busboard also works as expected, but don't count on being able to use every Zorro board available in the Zorro slots. However the "popular" cards works; I used a CyberVision 64/3D, a X-Surf ethernet card and a Algor USB Pro card in the Zorro slots.
