I have a 1985 Bally Beat the Clock. 500 units produced. Timed game that is fun to play.
While cleaning up the game I noticed that there are 4 flasher bulbs located up high in the playfield and 4 located in the backglass.
I changed the 912 bulbs out with new ones. They DO flash in test mode when performing solenoid test #92. However they do not flash at any point during game play.
I have noticed in at least one you tube video that these flashers will flash when the ball goes in the left upper saucer and when making it through the right side lane up to the top of the playfield. ( see 2:20 and 4:34 in this video of sample game play
) I have seen a couple other videos of games with no flasher action occuring during game play similar to my machine.
I have mostly EM's and just a few early solid state games so my knowledge is sparse in this area. I had a friend that is quite good with electronic pins take a look and we found nothing in the schematic contained in the game manual showing the flashers. When we did test #92 for the game all the flashers did in fact flash ! However nothing occurs during game play. We are thinking the lack of flasher action in my game is software related. It appears the original game rom is in the pin dated 11/13 (85)
Any ideas ?
