INTERLISP-D SUPPORT FOR XEROX 1108 FLOPPY DRIVE

     By Kelly Roach.  Last revised: Sept 27, 1983.
     Interlisp-D can now be used to read and write files from Pilot
formatted floppy disks on Xerox 1108 machines.  (Support for CP/M
floppies is expected.)  The procedures to use are as follows:
     (1) INSERT FLOPPY IN DRIVE.  Place an 8" double sided/double
density soft sectored floppy disk into the Xerox 1108 floppy drive
and close the drive door
     (2) (FLOPPY.FORMAT NAME).  Do (FLOPPY.FORMAT NAME) where NAME may
be an atom or string and will become the name of the floppy.  The
function FLOPPY.FORMAT initializes the floppy, erasing any old
information on the disk.
     (3) FILE DEVICE {FLOPPY}.  Use COPYFILE to copy files onto and
off of your Pilot formatted floppy.  Examples:
     (COPYFILE '{PHYLUM}<MYDIR>FILE '{FLOPPY}FILE)
     (COPYFILE '{FLOPPY}FILE '{PHYLUM}<MYDIR>FILE)
DIR {FLOPPY}* will show you the files that are currently on the
floppy.  All other familiar operations such as LOAD, OPENFILE, READ,
PRINT, BIN, BOUT, GETFILEINFO, SETFILEINFO, GETFILEPTR, SETFILEPTR,
etc. also work.
     (4) REMOVE FLOPPY FROM DRIVE.  Open the drive door to retrieve
the floppy.
     (5) ALREADY FORMATTED FLOPPIES.  A floppy created by (1)-(4) may
be reinserted into the floppy drive at any time so that files saved on
the floppy may be accessed again.  Just follow (1), (3), and (4),
skipping (2).  There are 2276 pages available for the user's files on
each Pilot floppy with the exception that there is 2 pages of
additional overhead per file stored.
