 -- part of original readme --

FS1541 is a full-blown AmigaDOS file system, which reads and writes the CBM
1541  disk  format.   The  CBM 1541 floppy drive has been the standard disk
drive  for the C64 computer series, and many people still have disks flying
around.   In  order  to  process  disks  directly, you need the >Catweasel<
floppy  disk  controller  and a 5.25 inch drive, without it you have to get
"fmsdisk.device" from Aminet or somewhere, which lets you operate on ".d64"
disk image files.
