Playmatic Chance MPU Problem
DarkSide:
Bit of an update.
Found out today the score switches and ball switch are on the same matrix, score switch is on 03, and ball switch is on 3B, both connected to the same 4072.
But i did change that, 3 times, also changed what was next in line a 4016, and a bunch of 4081 and 4042.
DarkSide:
Got it !
Finally, it was a floating input, missing connection between 2 resistors, machine is working 100% now.

Only my Chance, got a Party also but its missing a lot of vital parts so im just breaking it for spares.
Got to get rid of those two Playmatic's and start on my Jurassic Park instead.
