Stuffit 5.5: http://macintoshgarden.org/apps/stuffit-expander-55 first download should do the trick.
That was easy
iCab 2.99 (68k), System 7.5-8.1: GOD that was difficult! iCab itself can't fit on a floppy! I had to find a good backup program to backup the iCab disquette (available from developer's site). You can download
this and then do this:
1/ Write "SUM™ #2.image", "1.dsk", "2.dsk", "3.dsk" and "4.dsk" to 4 different floppies. Don't worry, I checked for viruses before linking them to you.
2/ Insert SUM™ #2 in your LCIII and run SUM Backup (optional: install SUM Backup ->just drag & drop, maybe easier 'cos you only have one floppy drive)
3/ Open SUM Backup.
4/ Click "<- Restore"
5/ Backup from: disk image 1 (i.e. insert floppy named "1")
Backup to: create a new folder on your HD
6/ Begin
7/ Insert the 2, 3, 4 when it tells you to.
8/ Done
Just tried it using mini vMac, it should work with your LCIII.

Tell me if it doesn't work.
