Hans,
I have the schematic, I have finished boards that I
have beem milling. I stopped selling controller boards do
to cost. I was hoping to get single sided boards made for
about $15. The boards are 4" X 6" and I used every trick
in the world to get all the parts on the board. The board
only has a few jumpers. When I tried routing programs two
years ago, they would create a two sided board.
That's when I started milling my boards. In order
to get boards made cheap, I have to do a large run. Thanks
for your help, I will give it another try. I have learned so
many programs since my BBS days, I feel like my head is going
to pop!
