According to my list, what you have there is a Monster Bash ROM board, and a
Monster Bash CPU EPROM, but the security chip is wrong. Possibly whoever you
got the boards from at one time tried to swap in a working CPU from another
game, not knowing about the differences in security chips.

The "meatball" soundboard is for Eliminator.

Some games had a few different software revisions. The best thing to do to
verify what you have is to archive the data and compare it to the EPROM data on
the arcade ROM data homepage (anyone have the URL for it?).
