Mesa 7i96S Daughter Card Question ... Can I use the 7i76U?

I read the  Which Mesa Card Should I Buy?  post and it was super helpful.

I wanted to buy a Mesa 7i76EU card today but they are out of stock. They are also out of stock on the 7i77 daughter card.

So, I hope to buy a  7i96S today, but I need to know what daughter board I can use to increase the number of inputs an outputs?

Can I use the  7i76U ?

I am doing a manual lathe CNC conversion. I'm eventually going to be adding a 12 tool ATC turret.

I have not finalized all the required I/O yet, so I wanna make sure that I have enough I/O for future updates to the lathe.

If I can use the  7i76U , I think I will have plenty of I/O for future updates, that may include​ ...

• a third MPG
• an encoder on the ATC turret for tool location/identification,
• a "Y" axis, three motor, four gang live tool option with an MPG (this last addition is way in the future if at all). 

Thanks,

Mesa 7i84 has 32 inputs and 16 outputs, it easily wires to 7i96S with a cut down LAN/network cable, CAT5 or CAT6 will do just fine.
Did you try
store.mesanet.com
and
www.mesaus.com
mesaus.com/product/7i96s/
has 29 in stock.

Yes, you can use a 7I76U with  a 7I96S  by using 7i96s_7i76d.bin firmware
and connecting the 7I76U to the 7I96S's P1 expansion connector.
 

Thanks for your responses! I ordered the 7i96S and the 7i84U.

Probably overkill in terms of the amount of I/O, but now I can go hog wild with panel buttons (just kidding).

Now onto picking components for the CNC lathe conversion!
