This is correct. Big Blue Reader comes in both C64 and C128 versions. > The reason that you can't read/write IBM disks with a 1541 (and conversely > that it works with both 1571's and 1581's) is that IBM uses a file > storage scheme alien to the 1541 (but which has been built in to the > other two drives along with the usual Commodore formats). I think it has to do more with the fact that the 1541 has only one read/write head, and so it can read/write one side of the disk at a time. > > Marc R.
