you took out one of the input chips on the cpu board, this is a typical trouble call, when the board jumper is not removed. need to look carefully, it does not look like a jumper, just a long piece of hard wire, i think it is in the J3 position, maybe J4, anyway if you are lucky, the input chips are in a socket, in which case you can remove the chip and replace with a new one, i have made this repair quite a few times over the years, replacing the chip will get the car back online, sometimes it will take out a couple of chips in the same area, if they are not in dip sockets, then you will have to have it repaired, or break out your soldering gun. good luck
