Ok after a little research this is definitively not a original Moon Cresta original cocktail, which sucks, but whatever.
After a little more research it seems that this board could have been a Moon Cresta originally, but it seems that these boards are really easy to turn into other games, and with all the work that has been done on this board I wouldn't be surprised if Moon Cresta wasn't on the board, and after a closer look there are eproms on the daughter board.
The Monitor doesn't work, Power supply doesn't work, and after close inspections about 4 roms lifted from the board. A mouse had been living in the bottom and some wires are chewed up inside the machine as well.
If this was an original Moon Cresta cabinet I would restore it, but it's not and there are a lot of problems. I'm going to see if I can find out what this cabinet originally was and if I can, try to convert it to that. I have seen quite a few games that have this exact cab but I would like to determine what was in this specific one. It looks as if the CP and the blue and yellow spaceship are original so I need to find what they belong too. I know I have heard of people saying that there are some generic cocktail cabs they could throw anything into, and I wonder if this cabinet is one of those.
Thanks for all the help behrmr, that button was manual degauss, and I have found about 4 pcb's for moon cresta, and none look exactly like this one....
The guy who sold it to me gave me a few papers he had with the machine, one was a moon cresta paper showing the differnt ships, one was a Tekken Tag schematic, and one was a power supply schematic for a different power supply than what was in this cabinet.... thanks guy.
