My understanding is that the 8 clot design does not correctly handle SLENB

The problem is IO pins.  Assuming a simple IDE interface, CPLD would 
otherwise work, but it takes almost 50 pins to do a 4 port MPI CPLD 
solution, and that leaves no pins for anything else.  FPGAs have more 
pins, but they are more expensive.

The problem with your current design is that it's so ambitious.  8 
slots, tons of embedded functionality, it's hard to get comfortable with 
the sheer amount of complexity.

Well, I contacted you in both places.
