old Mazatrol Cam T-2 to pc?

[4x4]

Sorry my bad English
We got an old (85-86mod) Mazak Slant Turn 50 – Universal 2000, with Mazatrol Cam T-2 software.

We are trying in blind how to get it work with a computer. This version of machine has microdisk hardware we can backup program. But the easiest way will be direct to my computer.
We got 2 ports in the side of the control (picture) . One for the diskette, and one for "hole-card"

I found out we got a button called DNC in/out, so i think it’s possible to a computer, but the nothing happens when i push this.
And the software we are trying to communicate with is DNC Precision (any other idea??)

we are just trying to backup / transmit and receive. No sim.
