So I have multiple switches firing all over the place on my Data East Guns and Roses. I have attached a image of the switch matrix. Here is what is happening as I can tell:
Pop Bumper 25 fires switches 25, 1,17,33,49 & 57
Pop Bumper 26 fires switches 26, 18, 34, 50 & 58
Pop Bumper 27 fires switches 27, 3, 11, 19, 43 & 51
Right Sling shot 28 fires 28, 4, 12, 20, 44, 52, & 60
Left Sling shot 29 fires 29, 5, 13, 21, 37, 45, 53, 61
So it makes for a very high scoring game
I am guessing I have a short or bad diode somewhere. Any help or thoughts is greatly appreciated.
