I have an Altered Beast PCB and marquee for sale. PCB is sold as is, game works but video is scrambled on it. I'm not sure how to repair, so I have no need for it. The marquee is in pretty good shape, will attach pictures of both.
I don't have any use for either of these, they are from an old Altered Beast machine that I converted to MAME. Make me an offer for 1 or both. If you have any questions, ask and I'll do my best to answer them!
