Quotethanks for the information, I have now contacted the Abb service point in Belgium. they said I had the wrong diskettes. I had the HD diskettes, but they had to be DD diskettes. This was easy to solve by putting a sticker on the second hole of the diskette. After doing this we could try again to load the diskettes but to no avail. Now it turns out afterwards that the diskette drive is broken. so I'm now looking for a replacement floppy drive.
