Since the author (classichasclass) seems to be reading the comments, I'll mention this here... The article mentions "The OpenFileService part provided a menu option which would dynamically generate a Cyberdog item to a file reference using the Standard Open dialogue [...] to the best of my knowledge is now lost". A file containing the OpenFileService part does seem to be available here, as part of Cyberdog 2.0 browser install[0][1]: * https://archive.org/download/cyberdog-evolt_browsers/2.0/SupportFiles/OpenFileService.sit https://archive.org/download/cyberdog-evolt_browsers/2.0/Sup... When it extracted it contains a folder named "OpenFileService 1.0.1 ƒ" which contains `OpenFileService` and a README file. I found this while investigating some other related items and will attempt to update/edit this comment with some links (but wanted to at least mention this now in case I disappear down some other rabbit hole :) ).

I found the above items on archive.org after initially looking on https://ftpmirror.your.org/ https://ftpmirror.your.org/ and http://bitsavers.org http://bitsavers.org which I've had success with in the past when looking for historical info/binaries, especially from archived FTP sites. While neither site appears to have specific archives of the CyberDog FTP site, I did find a number of OpenDoc & CyberDog related items (including SDK-related) which I'll aim to add links for below. * CW CyberDog Stubs & Includes: https://ftpmirror.your.org/pub/misc/apple/ftp.apple.com/developer/Development_Kits/Obsolete_Unsupported/OpenDoc_Development_Framework/Getting_Started/CodeWarrior_Development/CodeWarrior_Additions/INTO_CodeWarrior_Plugins/INTO_MacOS_Support_/INTO_Headers/Cyberdog_SDK/ https://ftpmirror.your.org/pub/misc/apple/ftp.apple.com/deve... * MPW CyberDog Stubs & Includes: https://ftpmirror.your.org/pub/misc/apple/ftp.apple.com/developer/Development_Kits/Obsolete_Unsupported/OpenDoc_Development_Framework/Getting_Started/MPW_Development/INTO_Interfaces%26Libraries/Cyberdog_SDK/ https://ftpmirror.your.org/pub/misc/apple/ftp.apple.com/deve... The above are under the "OpenDoc Development Framework" directory which contains a large amout of other related OpenDoc content which may be of interest: https://ftpmirror.your.org/pub/misc/apple/ftp.apple.com/developer/Development_Kits/Obsolete_Unsupported/OpenDoc_Development_Framework/ https://ftpmirror.your.org/pub/misc/apple/ftp.apple.com/deve...

(The relevant binary file is in the parent directory of the `.txt` file.) Hope the results of my research is of use to you or some future archaeologist!
