Retrofit CNC FROM FANUC O-M OT MESA

Hello everyone, I have an old CNC milling machine with an onboard FANUC O-M. The IO board and the MEM board are dead. I wanted to switch to LinuxCNC and MESA but I don't know which board to choose because I would like to keep my Fanuc servomotors: the three A06B-0141-B077 / αC12/2000 / 1.0 kW / 2.5 A, the SVM3 and my FANUC A06B-0855-B102 spindle motor (~7.5 kW).

No idea about the motors as they tend to have several types of feedback, but for a general idea of retrofitting such machines have a look here:

There are many more, lathe and a lot of plasma machines i have retrofitted, but this is more like yours, hopefully.

The Fanuc A06B-6102-H211#H520 spindle module, the A06B-0855-B102 SVM3 A06B-6080-H304 spindle motor, and the A06B-0141-B077 1.0 kW 2.5A X, Y, and Z axis motor, model alphaC12/2000. Thank you.
