The 0683 merely indicates the manufacturing week and year (week 6 of 
year 1983).  I don't know if the week number follows the ISO standard, 
but if it does, according to the calendar function of GNU Emacs, that 
would be 7th through 13th of* *February, 1983.  (The ISO week begins 
with a Monday.)

By the way, you can use cbmlink from to dump the 
firmware of the drive like this:
  cbmlink -c <cable> <device> -dms,0xc000,0 dos.prg -dmc,0xfc00,0 fdc.prg

Also, I'd like to archive any PET era test/demo disks in original disk 
image format (not as individual files).  Those can be copied with the 
cbmlink -dr (disk read) option.  Does anyone on this list have such 
disks?  I don't.
