PRECIX 4X4 CONTROLLER UDATE

Hi all , newbie here from the uk in desperate need of some help . Ive got a 2001 precix 4x4 machine that i would like to upgrade the motion control . Its currently using galli motion control boards which were upgraded some 8years ago from the linux floppy drive to ethernet ( before my ownership ). it has servo motors which i believe are Astromechs with renco encoders and the gold copley 800-760 drivers.
My question is can i replace all of the galli control boards and use an offline motion control system such as the SMS5-N-N and use both my current servo motors and motor drivers ????
ANY HELP WOULD BE MUCH APPRECIATED
MANY THANKS IN ADVANCE

Hi Andy thanks for your reply , can you suggest the Linux route please. ? Parts required to connect to existing dc servo motors and Copley corps 800-760 anologue drivers ? I’m grateful for any help /advise your able to offer . I opened up the control box last weekend to try and see what parts were used and it just looks a complete mess so I would really like to update it .

No info on drives , took 1 out the other day to take some info off it and took photo at same time . I’ve attached the photo

I switched my precix machine to linuxcnc, you can find my thread here:
