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:
filename.exe a:
Where "a:" is the 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!

Versions 1.00 to 1.2x are basically system-specific. Based on JDOS.
Versions 1.3x cover all models. Based on JDOS.
Versions 1.4x and later also cover all models and are based on DOS/V.
Not sure if Version 1.50 covers Model 5550-V2 or not.
Non-Japanese users, you'd better use 3070V150 if you have any of the systems above.
