I found a reference to this file at http://cd.textfiles.com/svdiamond/TEXT/DIR23, and sniffed around the file structure on that site until I found it. I couldn't get it to work, though. The .exe file unzips an .upg file, which Windows doesn't know what to do with. (I saw a hint somewhere that it MIGHT be for the OS/2, but have no confirmation of that.) Maybe someone more technical than I can do something with this one.
