Jim, Sherm, Regarding the artwork for the seismic preamp/filter that is shown at http://www.eas.slu.edu/People/STMorrissey/index.html, I can send a photocopy of the original artwork, 2X scale, black lines on white or a transparency copy of the actual printing film (which I doubt is dense enough to photo-print from), if you send me three stamps and an address. It really isn't that complicated, as you can see from the scan of the foil side of the board shown on the web site. But If I were to make only one or two, I would use perforated board with foil pads (Vector 3677 cut lengthwise), which I often do for prototype circuits.
