Where can I find a Forgotten Worlds upright arcade game for sale?

Question

I want to purchase one that is in excellent condition.

Answer 1

Okay simple answer keep looking on ebay for it it was released in 1988 by Capcon. You might have better luck looking to buy a working Forgotten Worlds jamma board on ebay then buying a jamma arcade cab from there too. then install the Forgotten Worlds board in the cab and play it that way.
If you know about MAME or would like to learn about MAME you could play it on your own computer.

Good luck
