1986 Bridgeport Milling Machine Centroid CNC 4

Hi, I have a 1986 Bridgeport milling machine with a Cardinal Cad Cam System, nobody seems to know anything about this system, I contacted the guy who used to sell the Cardinal system I was able to get the centroid software from him but he had no idea how the computer was to communicate with the motion controller, and he is the only one that sold these apparently. There will be pictures attached to this, what I have is a windows Vista computer which is compatible to the software, windows xp, windows 7 also compatible. There is a 25 pin connector that plugs into the motion controller and on the other end of that cord is a 9 pin connector, there are no examples I can find, what am I missing? A break out board? What would the 9 pin connector plug into? I’m trying to get it to communicate with my computer. There is also a start stop button right on the front of the quill and two wires that lead from it I have no idea what it would hook to. It’s a pretty nice machine yet and I have no idea how to get it going, any information would be greatly appreciated.
Thanks!

Centroid is still in business, call them?

Centroid will likely deny any knowledge of such a system.

I had one of these thirty years ago, it wasn't bad, but very limited. We ran it off of a laptop with a 386 processor. I upgraded it about year 2000 to Centroid M-40, changing the steppers to servos. A Centroid reseller purchased the old control.

IIRC, there was no breakout board required, it just plugged into the computers serial port. But, and this is a big but, there was a disc with driver software to be installed on the computer. Good luck finding that.
