The game board just locked up on me today with u18 being bad. I dont want to put any money in to this machine. I Picked up a better space shuttle and I would prefer not to part this machine out. Will not boot up and ball loader stopped working before the board locked up. Also has one dead display. Playfield is worn and when I got it the cabinet was poorly painted blue. System 9 boards are hard to find due to no replacements if no ones interested in whole machine I will part it out. Backglass has been taped over bubbles. Boardset works in 4 other machines only. Any questions feel free to ask. I am very close to six flags great adventure. Thanks for looking.
