Thanks to all who replied to my question about parallel port settings. I had set it to ECP+EPP when I first got the machine and did not think about it until I saw a post from another person. Let me say that setting it up as a standard parallel port ( SPP ) cured a little problem I was having with my programmer. I would have to unplug the board from my bread board setup and then turn off power for a few seconds. Then it would work until the next time I loaded the programmer software. Happy pic'n !
