I have an original Namco Rally-X pcb. Not sure if it works, and I don't have any way of testing it, but it looks clean. You specify cocktail, but I think that that is just a matter of a dipswitch setting. Or?
Interested in trading it for some of the following:
Taito Space Invaders control panel, Joust control panel (populated or unpopulated), Outrun board, Wonderboy board, Time Pilot board, Tempest board.
I live in Oslo, so depending on your location we might be able to do a trade in person.
