Of course it will work on your 14 MiB machine!  It fits on a floppy, _after_
decompression.  It was used by people to install Linux on the hard disks
of their beefy m68k machines, after they had set up the family Christmas
tree, in December 1996.

I also have a slightly larger one, built from OpenWRT when I did my first
experiments on that.  Unlike filesys-ELF-2.0.x-1400K-2.gz, it does open
a shell on the serial console, so it is more useful to me.

Will add to my todo list...
BTW, you can boot this ramdisk on ARAnyM, too.
