This information is gleaned from several sources. One is a photocopy
of a fax of a magazine article in German from 1993. Another is a copy
of the product information for the Panasonic AG-1960 5-pin protocol.
I have (not real clear) tiff copies of these pages available if you
want me to email them to you. If anybody cares to scan the TIFF files
in and convert them to text I'd love to have a copy. Text much
smaller files.
The TIFF files are:
- CTL_MTXT.TIF - a faxed copy of
the email from which much of this text is typed.
- CTL_M_G1.TIF - a faxed copy of
a page from a German Magazine.
- CTL_M_G2.TIF - a faxed copy of
another page from the same article.
- AG1960.ZIP - pages 1 through 11 of
a Panasonic product information bulletin on the AG-1960 5 Pin Protocol.
The original photocopies were faxed to my PC and converted to Huffman
compressed TIFF files.
The information has been typed in quickly. Please don't flame me for
any errors, just let me know so I can correct future versions.
