Could you specify a particular page in it for me to start with? If it could be around $25, your idea would certainly feasible. With the PCI card, commercial programmers can get rid of dangles. I had no FPGA experience. I got a question to hardware experts here: How difficult to implement it? Best Regards Dezhi Zhao
