Hi All,

I have several late 70's early 80's Williams games, the board connectors are an ongoing problem, is there an upgraded connector that doesn't use the knife style connector, maybe something I can actually solder a wire to and make a physical connection, thanks for the help,

Dave

What do you mean, knife style?

The kind that you have to push the wire into the connector and it cuts into the insulation creating a connection

I assume he means the IDC connectors? You can replace them with the crimp style molex connectors and replace the header pins.

Sorry, I don't know the terminology but I am talking about IDC connectors, do the molex line up with the existing circuit board holes?

For the most part Williams uses .156 Molex connectors. Look on here for them. You buy for the sizes you need.

I highly recommend picking up some connector parts (0.156 trifurcon pins and housings of whatever sizes you need--or buy big ones and cut to size) from great plains electronics, the link arcademojo posted. You'll need a crimper and wire stripper to install the new connector pins. This video does a really good job showing the procedure:

You don't solder crimp connectors - that actually weakens the connection.

The tool in the video pictured above does a great job - get one of those.

What makes it weaker?

More than you ever wanted to know about crimping molex pins. No mention of solder.
