did it years ago , so i can play Battlezone , of course it has damaged the control panel for Asteroids , but it was a compromise , as back then , i couldnt imagine finding a Battlezone upright , not around here in a hurry , but now im on this site , as long as i have funds , i reckon i could get most dedicated machines sent here , good thing is , the Asteroids CP is poor anyway , alot of cig burns , missing paint , so at some stage , i will get a good one sent over from the forum
