I'm working on my first restoration and looking for some help. I have a Williams Cosmic Gunfight (1982) System 7 machine.
The question I have is regarding the connector cables that attach to the power supply board.
When I bought this machine it apparently had the wrong power supply installed in it (looks like a system 6 power supply). There are currently 4 connectors that are not attached to any board in the system. I purchased the correct power supply board from Marco and I think I can match up the 4 connectors that aren't currently connected, to headers on the new board.
Two of the connectors look pretty obvious on where they should plug in but I'm stumped on the other two. It almost looks like 2 of them should be 1 connector but its split into 2 pieces. If I connect the two connectors to the header on the new board they fit on the single header. One of the two connectors is keyed and still seems to fit correctly onto the header and the 2nd connector fits right next to the first but they are sharing the same header which seems odd.
So I'm wondering if this is correct and if I have everything plugged into the right spots before I flip the power. The last thing I want to do is fry my new board or worse start a fire or something.
Below are some pictures of the old incorrect board which is still in the system, the 4 connectors that are not currently attached to anything and also pictures of the new correct power supply board where I am assuming the 4 rogue connections should be plugged in.
Also, I plan on installing new connectors before I do the final install. If the two connectors in question indeed both connect to the single header, should I purchase 2 replacement connectors or consolidate both of the old connectors into a single new connector?
Could you guys please let me know what you think? Any help would be much appreciated.
