I think your board is fixable, as it is almost working. I've been reluctant to offer suggestions on your repair thread, as I don't know what I'm doing and I don't want to screw you up more. Keep bumping it and someone should be able to help out.
You do have some other alternatives though.
You could always get a multitaito board and have access to zoo keeper and a bunch of other games. I think you've got to convert the cabinet to jamma, but it would get you running.
Also, not that Qix boards are that much more common, but I just scanned the Qix to Zoo Keeper conversion manual I found in my ZK. Converting the board involves replacing the roms, cutting 2 traces, and jumpering 2 spots. If you weren't comfortable doing this, I'm sure someone on here could do it for a reasonable price.
