The Livingston Portmaster 11 uses an internal 720k diskette drive.

HERE IS HOW TO COPY A PM 11 Diskette

On a unix host:

dd if=/dev/rfd0 of=pm11_24_image bs=18k

to copy the disk from the pm11 to another blank (pre-formatted) diskette.

To make a copy the other way:

dd if=pm11_24_image of=/dev/rfd0 bs=18k


There is no way to do it as far as I know on a DOS/WINDOWS machine. You may
be able to use RAWRITE to write a disk image to the disk.

One other note. I think you are really supposed to use bs=9k since its a 720k
disk and not a 1.44 but the above instructions are per BRIAN RICE at
Livingston. The output shoul write 80 records, so if it is NOT 80 records,
then use bs=9k
