Thanks for the quick response.
I have a question again. Before I place an order. I'm looking at a board. 7i98 - There are 51 inputs/Outputs
Are there any examples of how to make a custom bit file. For example, connector P1 should have 3 analog outputs (+ 10 / -10) and 3 inputs for encoder + index. and one out for RS422 (for controll panel)
Connector P2 and P3 configured as LPT
Can it be done by an ordinary person. :)

If it can be done, I will buy two sets and these boards are available in the EU

Yes, you can make your own bitfile. It's generally easiest to start with something close and modify it.

It's worth looking through the existing bitfiles and vhdl for other 51 pin cards (vhdl files like PIN_***_51) in the source:

Look in configs/hosmot2/ and configs/hostmot2/source/hostmot2.zip (needs to be expanded)

Thanks!
It seems half the job is to find the right files. :)
I ordered the cards. I hope I can handle this job.

A little update. The cards will arrive next week. 2 pieces 7i98 and 2 pieces 7i73. I installed ISE14.7 and successfully compiled the firmware. It remains to make a bit file for my custom pcb board.
Each 26 pin connector has 17 I/O but must be in this combination /12 Input and 5 output / or / 12 output and 5 input/ or /17 input / or / 17output /?
Or each pin has a choice of direction ?

Yes, on most of the Mesa boards. I am sure 7i92 does that, not sure about 7i98 but i would venture a guess at yes.
