Just before I dive into knowing these boards deeply (if it is possible 
without having them) I want to clarify some things:

1. Can several anything I/O MESA cards be used together?
2. How flexible output assignments are? For example, is it possible to 
run these:

7i43-P Anything I/O parallel only - 200K FPGA - 48 I/O
7i39 Dual 3 phase BLDC motor driver
7i30-4 4 axis 3A servo motor Hbridge for Anything I/O

3. 7i43 + 7i39 + 7i30-4, but use only one 3-phase motor driver, only 2 H 
bridges and other pins for general I/O (provided that I will connect 
everything accordingly)?

4. Or take 7i43, two 7i39 and run 4 BLDC servos in sine commutation mode?

5. Use MESA cards together with second parallel port for other general 
I/O, stepgen.

6. Powering 7i39-H. I am planning to use regulated 48V PSU, but.. if I 
would make unregulated supply, how to select suitable transformer (type, 
voltage)?
