Is anyone using the Mesa 7I42TA to interface with the Mesa FPGA boards?  
I've got a couple of questions if anyone using the board already would 
have time to answer.  I'm trying to figure out everything I need to 
order to get it up and running.

Is it good enough for interface with servo drives and limit switches or 
do I need more protection like optoisolators?  My servo drives from ebay 
arrived and the servo drive inputs are opto isolated in the drive.  Do I 
need two optoisolators, one in the drive and one to protect the mesa 
fpga board?

Are the input pins pulled up to +5V?  Or do i need external pullup 
resistors for encoders and limit switches?

Is it just the 50 pin ribbon cable that connects the 7I42TA to the fpga 
board or do I also need to supply external +12V and -5V for the diode 
clamps?

Thanks!
