The pop bumpers and flippers are not controlled directly from the driver board. Flippers are enabled via relays (which are in turn activated by the driver). Make sure the Q, U, and T relays are activating properly.

Pop bumpers are controlled via separate pop bumper boards, and also have their voltage cut off from the T+Q relays like the flippers.

The lower playfield upkicker is controlled by the K relay instead of a driver transistor.

The lower playfield drop targets are controlled via an underplayfield transistor.

Since so many things have failed it seems unlikely that it's just the driver board. Do you have voltage at all the coils? Have you checked all the fuses? Gottliebs have a lot of fuses all over the place..
