Ed. Tom (20 Sep 2020): I've contacted Sandy
(the original author of the PS/55 pages) regarding the missing files,
and much to my amazement, he not only replied, but actually managed to recover
most of the missing files from his old backups (even after all these years!).
And I was able to find the few remaining files elsewhere. So, I'm happy to
announce that all links below are alive again! Special thanks to our PS/55
Hero - Tatsuo "Sandy" Sunagawa.

Creating and Restoring Floppy Images
You can create image files of existing floppies or vice versa using one of following programs:
Most ZIP files listed here contain self-extracting EXE files that when executed will create the corresponding floppy disk (Ref, Diags, etc.).
Use the following syntax to run the executable (without the quotes):
filename.exe a:
Where "a:" is letter of the target floppy drive)
Files with the LZH extension are compressed using the LZH algorithm. To extract them use LHA.exe or some modern alternative.
Disclaimer: Some of the files on this page were not tested! Use them at your own responsibility!
