Followings are mainly for Japanese Enthusiasts if there still is ( are )...

R & D for PS/55 are no more available at PC DOCK. 
But here, you can DL any you want...Until FBIbm will detect.

If you have anything other than listed below ( of course relating  "pi : es go-go" ),   please send image file to me ( remove spamblock ) 

How to create image files of floppies. 
You can make image files using one of following programs with which  you can convert whole contents of floppies to image files . 

  1. VFLW ( Win95/98 Win NT/2000 )  This is for Japanese readers. Very easy to use.
  2. LOADDSKF/SAVEDSKF       (  Japanese readers can down load at VECTOR  )
  3. If you have DiskExpress, it's fine.  Trial version is here.   Or click here  to buy. 

Sorry for inconvenience !

I'm afraid but most of following links for programs are not activated this moment.  I have deleted the files from ISP's server because whole contents has exceeded the capacity allowed to me.  If you need any files listed below, please let me  know ( need delete dot spamblock ),  I'll put them on temporally so that you can down load .

Please note
  1. ZIP files will create self extracting files with EXE ( exe ) extension for R and D.
    Please run the exe file using syntax like "xxxx.exe a:" ( a: is where you put a  blank floppy ) otherwise noted.
  2. Some files are compressed in LZH format.  You need Lha.exe to extract such files.
  3. I have not tested some files stored below myself. 
    Please use files with your own responsibility.
