The Internet Old-Time Radio DigestTo facilitate the encoding and decoding of the Internet Old-Time Radio Digest, we make available a facsimile of the 1945 Captain Midnight Secret Squadron Code-O-Graph in two versions; an Adobe Acrobat version of the Code-O-Graph (for the latest free Acrobat Reader, see Adobe Systems), and a straight GIF version. If you have the reader, the Acrobat version will make a MUCH better printout.
1945 Captain Midnight Secret Squadron Code-O-Graph
Instructions are on the printout.
UPDATEFor those who may be confused about how to use the Code-O-Graph after assembly, please see this manual page which should explain things more clearly. (Much thanks to Stephen A Kallis, Jr. for the scan!)
