Can someone confirm composite sync wire color for Missile Command edge connector?
This Missile Command I picked up, no one was able to figure out why some chips on the PCB kept blowing up. I found that someone appears to have put the composite sync into pin "Z" and then tapped in the negative/ground to controls into the same. What I have confirmed, is a green/white wire that is now in pin "Z" that when tested, goes to molex connector into monitor. Then there is a black wire, that was spliced in, that I have tested goes back to the CP start/control buttons. If I get this back to how it should, replace the blown chips on PCB, then this baby is up and running!
