Game is awesome...I remember when it was new in the arcades the lines of people playing it. Haven't seen a board for it in awhile, looking for the complete game though. Good Luck.. And it's Strider.....
Good luck with your search. They are out there, but not too common. I picked-up a conversion years back for $90 (working). The rest of the parts went to other folks to complete their games, but I kept the PCB. It's a great game IMO.
