MYSTERY 5.25 inch external floppy disk drive - What is it for and does it work ?

I got this 5 1/4 inch external floppy drive that was completely unknown. PCBWay https://www.pcbway.com/setinvite.aspx... - great quality PCBs from just $5! The drive is labeled COMBITEC, but that is all I knew when I got it. The Internet did not reveal much, so that means that I have some exploration do to to figure out what machine(s) this can be used for and if it is still working.
