haha awesome man, I had no clue it was a punch out, I would like to restore it to original, and put my Golden Axe pcb into another cab. But it may be difficult to find parts and what not. all the wiring is there. As for the joys I ill try soaking them tonight and see if they loosen up. Thanks for the reply.

If it is wired for Golden Axe (Sega System 16 pinout) then, unless they used an adaptor, the wiring is most likely either hacked or replaced altogether.
You would obviously need a monitor for the top. The correct monitor is a Nintendo/Sanyo or Nintendo/Sharp (another of the same kind that is in there already).
Your control panel has been Swiss-cheesed obviously. Those are repairable, or you could look for an unhacked used Punch-Out CP to buy. High quality screen-printed reproduction Punch-Out control panel overlays are available from Quarter Arcade for $45 (they also have reproduction Punch-Out sideart).
I assume that the 120 to 100 VAC transformer is still in the machine, given that the original monitor which requires it is still there.
What about the power supply? Is it a replacement "switcher" or is it the original Nintendo power supply?
