I've been working on a S-100 proto board design recently. I like to say thanks for all the suggestions that everyone sent. I updated the page to include images of the pcb design and the cad design(3D) Anyone else that might be interested in this, I can add your name to the list on there. You can see the current work on my homepage. http://ragooman.home.comcast.net/rog.html =Dan -- [ beauty is in the eye of the beer holder ] [ http://ragooman.home.comcast.net/ ]
