OS disks for HP150A

Hello, I wonder if anyone can help me. I have an early 1980s Hewlett Packard HP150A which I am trying to find a home for in a museum. The system is working but I can't find the MSDOS (or application) disks for it which were on 3.5" floppy. Does anyone know a source of such things? I think I may have a museum interested but I would rather donate it as a fully working system.
