Deckel Retrofit FP4A

So, in the end my shopping cart will look like this: 

1. 7I92TF
2. 7I83
3. 7I84 sourcing outputs
4. 7i85

This should be enough to start up the machine with current configuration? 

Just one thing is not clear. For which purpose do we use card with FPGA? Sorry, maybe the questions are dummy, but i am noob in this area.

7i92TM would be better as it plugs directly to 7i85 so no cable needed.
FPGA takes care of the complicated stuff like, generating steps, counting encoders, etc, at very, very fast rates.

Hi, i got info that 7I77 will be available maybe next week in EU. I dont know if advertising is allowed but there is one european site for MESA boards ordering.

So my question would be, should i keep the combo, or to replace one part with 7I77?

Also, what consernes me is that Inputs on 7I77 are sinking. And i think that i have PNP or sourcing sensors on my Deckel?

www.eusurplus.com and www.welectron.com are in Europe, Portugal and Germany respectively.

Sinking inputs work with sourcing (PNP) outputs
