Chris,
Three people copied the HobbyCNC board. All three went down in
flames when Dave came out with the new board. It made my day! You can
search every magazine in the world. I was the first to use the window
channel. The scraps never made it into the hands of the public. You
remind me of the people who said swaping MP3s were going to help the
record industry. I am in the process of looking for a job. There won't
be any new designs (old ones according to you) coming from me in the
future. I took a bunch of old ideas and made something new out of
them. In six years nobody has done anything as slick.
