I've looked at 100+ CPU boards, and every one of them that had a round
yellow sticker over the security chip was for Eliminator 2-player. Other
than that, I've never seen any other types of stickers on the security
chips.

The wire mod on the back is fairly typical (about 50% of the time).

About the only thing that will tell you is its not 315-0064, but will not
tell you if it's one of the other 4 or 5.

Nope, and if I had, I'd have thrown it away :-). However, every so often
I'll see a board where a large portion of the chips (like a block or row)
have been socked...usually on the XY pair or the Universal sound board.

I have all of them except Zektor, and you can pick one up in 10 minutes if
you win the Monster Bash auction on ebay...
Let me know what you need.

If anyone needs anything Sega G80 related, feel free to ask.
