Retrofitting a TOS FNG 32 NC

@Henk
Mesa 7i77 has two MPG encoder inputs in addition to 6 high speed encoders.
7i76 and 7i76E also have two MPG inputs.

I will use an office computer that I have so I have lots of space, 
Yes, it looks likes many of the cards like 7i97 and 7i92 and many more is out of stock. 

7i77 seems like a good option, is it compatible with the 7i94?

The outputs that I need and can think about right now is the gearbox with 3 gears, cooling water and possibly some warning lamp. + all the ones I dont know that I need yet 6 would probably work but it seems to me to be a little low. 



 

7i77 and 7i94 is compatible.
I would add a 7i70 as well, available from eusurplus.

I have used this combo on a maho mh600c recently.

Okey.
How are they connected though?
I only see RJ46 connectors on the 7i94. Do I need some special cable connected to the 26-pins on the right side?

You need a standard ribbon cable with a 26pin idc connector on one side and a db25 connector on the other side. I normally get the connectors and ribbon from my local electronics store and assemble it myself. You could probably get one from mesa as well.

Mount the 7i77 and 7i94 close together to keep the ribbon cable short as possible. Stay as far away from the servo and spindle drive as you can.
