I uploaded the program READ6530 to funet some time ago. I don't know where it ended up. It will copy the contents of the 6530 ROM to a disk file. > I'm not at home right now so I cannot check the manuals.

The number of sectors on a track is defined by a paramater table in DOS. There is no difference in the drive mechanism itself. The 2040/3040 has 20 sectors on tracks 18-24. The 4040 has 19. The reason given for the change was that 20 sectors did not leave enough of a gap between the last sector and the first one. - This message was sent through the cbm-hackers mailing list.
