To make a 360k floppy in Linux:

  fdformat /dev/fdXh360
  mkfs -t msdos /dev/fdXh360 # or
  mkdosfs /dev/fdXh360

 on my Debian box, with a standard 1.2M 5.25" drive. "X" is the drive
#. On older Slackware, IIRC, it was fdXH360, so you might wanna check.
  So let me get this straight. I have a 128D, with an external 1541.
Assuming that the 6-pin DIN male-male cable that came with it is right,
I can format a DSDD floppy in the 1541, and read files from a 360k DOS
floppy to the Commodore-formatted disk.

  In my googling for the pinout of the above-mentioned cable, I came
across some plans & software to attach a 1541 drive to a PCs parallel
port. Has anybody tried it?
