IBM 5535-M18 Multistation

Below are some pictures of a recent acquisition; the IBM 5535-M18 Multistation with 3274 terminal adapter.  This was a business PC from Japan that also acted as a word processor and a terminal.  Sadly, the hard drive is not working so I am unable to boot it.  I am currently looking for a DOS K2.00 3.5″ floppy disk image and software, if it still exists.
