The original connector is often broken on surviving 067-0589-00's. This can be due to bent or broken off contacts, or because of brittle plastic side covers that no longer supply enough pressure on the contacts to keep them engaged.
It is possible to replace the original connector with a modern card-edge connector, from which the mounting flanges (if any) have been cut off. Remove the plastic side covers from the original connector and de-solder the contacts (fine pliers help). Remove the remaining plastic connector skeleton, cut the center piece out to retain the mounting flanges that hold the PCB in place. Use these to help with the mechanical alignment of the new connector. Bend the pins of the new connector as needed and solder to the board.
