Hello Christopher,

   I think that you're maybe the third or fourth post on this list in 
over six months...this list is pretty dead...everyone overloads the main 
rc5 lists with hardware information...it's really annoying....I think 
you should post your message to that list (rc5 at lists.distributed.net) 
and ask people to reply to this list (i.e. 
hardware at lists.distributed.net).  I have asked a couple of people about 
FPGA's and how to get them working, what they cost, etc. as I was 
interested in trying them on my own but haven't received any successful 
responses yet. Would you mind giving me/us a little more detail on how 
you have your FPGA's set up, how you programmed them, connections to the 
PC, cost, etc.? Any help will be greatly appreciated.
