MGSmith: 1. Others have pointed out to me that this NG is "non-binary" i.e. no .jpgs etc. 2. The scan was/is atrocious. Post it on one of the alt.binaries... NGs or someone's website after you've got the scanner sorted out. Also, BTW, would that diagram not be subject to 2 layers of copyright - PTC's and the magazine's? DW
