Someone asked me why I sold my cable, actually I bought pronto from Matthew, from this site. Everything was in it except the cable, he promised to send it right away, but I could not wait, so I bought some parts from electric shop and made it myself. It cost me about $10. It work perfecty. I programmed from prontoedit and download to the pronto through this cable. I'm using the pronto now. I believe I will receive the original one from Matthew soon, and I will not need the cable I made. Thank you.
