Once I have the three EMC files on disk, the next thing I'd do is make a directory called /usr/local/nist on the Linux machine.
mkdir /usr/local/nist
Now move into that directory.
cd /usr/local/nist
The prompt should show nist on the right end. You can stay in this directory and copy files to it. Insert the first floppy into your machine.
mount -t msdos /dev/fd0 /mnt/floppy
After a second of looking at your floppy it should return your screen to your root prompt. This mount command will allow you to work with floppy files in your /mnt/floppy directory. If you have already defined /dev/fd0 as having the msdos file type you may be able to skip the -t msdos part of the above command.
cp /mnt/floppy/* /usr/local/nist
After a bit of floppy disk grinding you should get the prompt again. Check to see that the file was copied.
ls
You should see a list of the files in the nist directory. At this point there will be just one emc-**-***-1999.aa* if you copied it.
umount /dev/fd0
After a second you should get the prompt again. If you get a "can't umount message" it is probably because umount will not work when you are in the /mnt/floppy directory.
When umount is successful you'll need to repeat the mount, copy, ls, and umount commands for each of the disks. You don't need to type in each command every time, at the prompt, he up arrow will scroll you back to the previous commands. Just up arrow to the one you want and [enter].
Now that you've got a directory listing all of the emc floppy files in it, all you have to do is put them together. You can do this with the cat command. It will be easiest if your prompt and the files are in your nist directory.
cd /usr/local/nist
Type in:
cat emc* > emc-dd-Mmm-yyyy.tgz
(you should replace the dd-=Mmm_yyyy with the proper release numbers.) After a bit of work you should see the prompt again.
ls -l
Those are lower case L's not one's. The big tar file should be listed as a 3+ meg file with the .tgz extension.
