原创 Spartan 3A DSP Starter board download cable

I've got this board for two weeks. but did nothing except power on.

Xilinx makes some trickinesses on download cable to push the user to order USB JTAG 

download cable which asked USD200.    

I think parallel port / jtag (III) download cable can does this work also, just slight modifacations are needed on voltage convert/shift.  

There are some clues in following link to overcome those difficulties.
