The Zorro slots cannot use IBM style cards. The IBM style slots found in
the 2000/3000/4000 were designed to be used with the BridgeBoards. The
BridgeBoard being essentially an XT, AT, or 386SX clone on a card.
At one time there was a card marketed that would allow you to access IBM
cards in the IBM style slots. However you needed drivers to do so. I
doubt that it is sold any longer, and unsure of what drivers were ever
written for it.
