Hello - this is a newbie's first post. I'm trying to source the right male molex connector for the GI connection (J9) to the power supply on a Williams #Comet.

My original power supply was burned and hacked with the GI wiring soldered directly to a big mush pad of solder and jumper wires on the supply. When it finally died, I replaced it. The new power supply has a squeaky clean female connector to plug into, but I don't have the male. I assume the last owner cut it off to make the direct solder connection.

There are several 2-pin male molex connectors described as "Williams GI" out there that could be it, and I think I have now bought them all... except the correct one. I can't find a part number in the manual. I can't find it when searching my machine's name (and other system 9 games) on Marco. This power supply is used on multiple Williams MPU systems so I cant figure out why I'm having so much trouble. Does anyone know the part number or have a link to the right one? Thank you for any help!

The mating connector is Molex # 19-09-1029 available here:

It uses female .093" crimp terminals:

Use Molex # 02-09-1104 terminals.

The original GI connector is soldered to the board with no molex. So yours was original.
